The Incredible Jimmy Smith

The other day I was re-shelving my copy of guitarist Johnny Smith's fine 1968 release titled Phase II.  Since my LPs are alphabetized by last name, right next to Johnny Smith was Jimmy Smith, the wizard of the Hammond B-3 organ.  I'm a big fan of Jimmy Smith, and since I hadn't listened to any of his albums for a while I took a couple down for a spin.  They were so hot and funky that after the first two I pulled out a couple more, and then a couple more.  Next thing you know it's three days later, and I'm still listening to Jimmy Smith.  To quote from the title of one my favorite Jimmy Smith albums, Damn!

The Incredible Jimmy Smith at the Hammond B-3

Smith was born in the Philadelphia suburb of Norristown on December 8, 1928.  As a child, he learned some piano from his father, but was largely self taught.  While just a teenager, he began playing gigs in the Philadelphia area, earning a reputation for his stride style technique.  When Smith was 15, he quit school and joined the Navy where he played piano and bass in a segregated Navy band.  After his enlistment was up, he came back to the Philadelphia area to study music on the G.I. bill and once again began gigging in clubs.  Beginning in 1951 and continuing for several years, he played off and on with an R&B group called Don Gardner's Sonotones.

In 1953, Smith heard Wild Bill Davis (below), a pioneer of jazz organ, at the Harlem Club in Atlantic City.  Davis' playing had such an impact on Smith that he decided then and there to switch from piano to organ.  After the set, Smith had a chance to talk with Davis and told him about his decision.  Davis cautioned Smith that it wouldn't be easy, warning that it could take years just to master the foot pedals on the organ.  Undaunted, Smith spent the next couple of years continuing to play piano at night in clubs while teaching himself to play the organ during the day.

In a 1994 interview with former Bay Area DJ and B-3 aficionado Pete Fallico, Smith explains how it worked:  "I got my first organ from a loan shark and had it shipped to a warehouse.  I stayed in that warehouse, I would say, six months to a year."  Smith says he treated it like a job, packing a lunch and practicing all day by himself.  "Nobody showed me anything, man, so I had to fiddle around with my stops."  In the end, Smith says, "I pulled out that third harmonic and there!  The bulb lit up, thunder and lightning!  Stars came out of the sky!"  Fallico comments that "Jimmy emerged from that warehouse a new and different organist with a truly original approach and registration. His new sound would prove to be the standard for Jazz organists who followed."

By 1955, Smith was ready to strike out on his own, working with a drummer and guitarist in what would become his signature trio style.  In the summer of that year, Smith was back in Atlantic City to play some dates - this time with his own trio - and the jazz world began to take notice.  Babs Gonzales, a jazz vocalist and well-connected NYC music writer, says that when Smith opened in Atlantic City, "Within three days the news reached me about this insane organist, and I drove down to "dig" for myself.  What I heard was a cat playing. . .futuristic stratospheric sounds that were never before explored on the organ."

Gonzales got word to Alfred Lion at Blue Note Records and told him he had to hear this dynamo named Jimmy Smith.  Some months later, in January 1956, Smith and his trio played their first New York gig at Small's Paradise in Harlem.  They followed that with a date at Cafe Bohemia in Greenwich Village, where Alfred Lion was in the audience.  Lion was blown away by what he heard and immediately signed Smith to record for Blue Note.

Lion wasted no time getting Smith in the recording studio.  On February 18, only a few weeks after the show at Cafe Bohemia, Lion booked a session for Smith at Rudy Van Gelder's studio in Hackensack, N.J.  Along with Thornel Schwartz on guitar and Bazeley "Bay" Perry on drums, Smith cut ten tracks at his first recording session.  Nine of them ended up on Smith's first Blue Note release (BLP 1512), titled A New Sound - A New Star - Jimmy Smith At The Organ (above).  [Fun fact: Gonzales wrote the liner notes for Smith's first Blue Note album.]

As an indication of Alfred Lion's commitment to Smith and his confidence in Smith's marketability, the first release is billed as Vol. 1, and the back liner lists the cuts for the upcoming Vol. 2, which would appear as Blue Note BLP 1514 only a month later.  In all, Blue Note released five albums by Smith in 1956 and another seven albums in 1957.  Eleven albums in two years' time!  Before Smith left Blue Note for Verve in 1962, he had put out 19 albums.  But Blue Note wasn't done with Jimmy Smith.  Lion had plenty of unused session tracks in the vault, and the label put out 10 more albums by Smith over the coming decades, including a final album in 2007 called Straight Life containing unreleased tracks from a 1961 session.

After moving to Verve, a bigger label with a bigger budget and more promotional muscle, Smith's popularity and sales grew exponentially.  In contrast to his trio and small group recordings at Blue Note, legendary Verve producer Creed Taylor put Smith in the studio with large bands and crack arrangers like Claus Ogerman, Oliver Nelson, Gerald Wilson, and Lalo Schifrin, creating a more contemporary and marketable sound.  Smith's first album for Verve, called Bashin' (left), made it into Billboard's Top 10 album chart.  Over the next six years, Smith had an incredible 18 albums in the charts.  You could probably win a bar bet by challenging someone to name the best-selling jazz artist of the 1960s: It was Jimmy Smith by a mile.

An unbylined obituary on the NBC news website nicely sums up Smith's place in the jazz Pantheon.  "Although Smith wasn’t the first to play jazz on the Hammond B3 organ, his virtuosity over the instrument combined with his brilliant infusion of gospel, blues and R&B riffs and melodies into bebop-inspired improvisations place him alongside other jazz pioneers, such as Charlie Parker, Art Tatum and John Coltrane – artists who revolutionized the way their respective instruments were played and who are continuing to have a profound influence over other instrumentalists."  

According to Discogs, Smith released 107 albums during his lifetime, not counting compilations or guest appearances on other artists' albums.  I have 37 of his LPs, and another 50 or so CDs ripped to my computer.  Since there is some overlap between my LPs and CDs, I am still missing at least 30-35 albums.  Sadly, a number of Smith's later releases have never appeared on vinyl, including the aforementioned Damn! (right), which came out in 1995 on CD only.  [Damn! features a killer version of James Brown's classic "Papa's Got A Brand New Bag," which is worth the price of admission all by itself.]  The sessions for Damn! (and a subsequent album called Angel Eyes) were the last times that Smith recorded for Verve.  On the off chance that anyone at Verve ever sees this, end the madness and release Damn! on vinyl.

Smith's early Blue Note LPs are the most prized by die-hard bebop fans and are by far the most collectible.  The good news is that even the deep groove, mono first pressings of Smith's Blue Note albums can usually be found for a couple of hundred dollars or less - which is very reasonable by Blue Note standards.  Reissued versions of Smith's Blue Note catalog are also available and reasonably priced for the most part, although finding copies in NM condition can be a challenge.  Smith's Verve output sold so well that original releases in nice shape are not hard to find; I see them pretty regularly for $5-10.

Last fall, Blue Note reissued Smith's terrific 1964 album Prayer Meetin', which features tenor saxman Stanley Turrentine (below left).  It's part of Blue Note's wildly successful Tone Poet audiophile reissue series, and is well worth picking up before it sells out.  Blue Note also recently announced a reissue of Smith's 1963 classic Back At The Chicken Shack (below right) as part of a different series called Classic Vinyl Edition.  Both of these reissues are cut by Kevin Gray using the original master tapes.  Chicken Shack is due out in June, and is available for preorder now.  I've already reserved my copy.

Verve Records began its own classic jazz reissue series in 2020, but so far they have not announced any albums by Jimmy Smith as part of the lineup.  Damn.

Enjoy the music!

LP Pressing Rings And The Mystery Of The Deep Groove (11/2023 Update)

NB: November 12, 2023 Update.  A big refresh with lots of new plants, updates, and corrections.  As always, this is a work in progress.  Corrections or additions are gratefully accepted.

------------------

In my December, 2016 post, I wrote about how to decipher some of the information in the dead wax in order to figure out such things as which version of an album you have, who cut the lacquer, where it was mastered, and which company pressed the LP. I mentioned that the size of the pressing ring can also be a good way to help determine which company pressed an album. With a number of new pressing plants coming online and a big increase in the number of albums being pressed in Europe, I thought it might be useful to look a little deeper at what the pressing rings can tell us.

Click on the photo to see it larger.

Above are three different pressings of Crosby, Stills, Nash & Young's 1970 hit record Deja Vu. Atlantic Records is a great place to start because they always list the pressing plant on the label. As opposed to many of the other big labels, Atlantic didn't own their own pressing plants. So, they had to contract out for all their releases. At the bottom of every Atlantic label is a number, in the case above, ST-A-701829 [not to be confused with the LP's catalog number, at the top of the label, which is SD 7200.] Atlantic's numbering system is pretty straightforward. In the example above, ST = stereo, A = Atlantic, 70 = the year, and 1829 is the tape master number used to cut the lacquer. After the tape master number is a (mostly) two-letter code that indicates the pressing plant for that particular copy. Here is Atlantic's list of pressing plants:

AM = American Record Pressing Co., Owasso, MI
AR = Allied Record Company, Los Angeles, CA
BW = Bestway Products Inc., Mountainside, NJ
CT/CTH = Columbia Records Pressing Plant, Terre Haute
CP = Columbia Records Pressing Plant, Pitman, NJ
CS/CSM = Columbia Records Pressing Plant, Santa Maria
DCE =  MCA Pressing Plant, Gloversville, NY
DCW = MCA Pressing Plant, Pinckneyville, IL
FT = Fidelatone Mfg., Hawthorne, CA
LY = Shelley Products, Huntington Station, NY
MG = MGM Records Division, Bloomfield, NJ
MO = Monarch Record Mfg. Co., Los Angeles, CA
MS = Midsouth Records, Nashville, TN (rare)
PL = Plastic Products Company, Memphis, TN
PR = Presswell Records, Ancora, NJ
RI = PRC Recording Company, Richmond, IN
SO = Sonic Recording Products, Inc., Holbrook, NY
SP = Specialty Records Corporation, Olyphant, PA
W = Columbia Records Pressing Plant, Carrollton, GA (rare)
WM = Midwest Record Pressing, Inc., Chicago, IL

Pressed by Philips Record Corp., Richmond, IN

If you click on the photo above to enlarge it, you can clearly see that the codes on the three copies of Deja Vu from left to right are MO, PR, and RI. That indicates that the three albums were pressed by: Monarch Records, Los Angeles; Presswell Records, Ancora, NJ; and Philips Recording Corp., Richmond, IN. However, even if they didn't put the code on the label, we could probably figure out the pressing plant anyway, either by looking for MR, PR, or PRC in the dead wax, or by checking the size of the pressing ring -- as long as you know that the pressing rings for Monarch, Presswell, and Philips are 73mm, 32/70mm, and 70mm, respectively. 

When record presses squeeze a biscuit of vinyl, they create a pressing ring (or rings) on each side of the label. The size of the rings depends on the size of the die that the pressing plant used to hold its stampers in place.  Luckily for us, many of the major record manufacturers have different sized rings, which often allows us to figure out where a record was manufactured even if there is no indication in the dead wax.  

In the heyday of LPs - the 1960s, 70s, and 80s, the vast majority of US releases were pressed by plants owned by the major labels such as Columbia, Capitol, and RCA, or by the major independent manufacturers such as Specialty, Rainbo, Monarch, and Presswell. In order to cut down on shipping costs, most major labels had pressing plants in different parts of the country -- typically on the East Coast, in the Midwest, and on the West Coast. Columbia Records, for example, had pressing plants in Pitman, NJ, Terre Haute, IN, and Santa Maria, CA. I live on the east coast, so most of my Columbia albums are from Pitman. [Columbia also had earlier plants that closed in the 60s in Bridgeport, CT and Hollywood, CA, as well as a plant that opened in 1981 in Carrollton, GA.] And just by the way, LondonJazzCollector has a terrific post about the history of the Columbia label.

RCA had three plants in Rockaway, NJ, Indianapolis, and Hollywood, CA, (although Rockaway and Hollywood both closed in the 70s). Other labels had more or fewer plants. Capitol had four plants, in Scranton, PA, Winchester, VA, Jacksonville, IL, and Hollywood, CA. MCA and United Artists had two plants each.

Like Atlantic, Warner Brothers did not press their own records. From 1958-1963, most Warner albums were pressed by RCA at their Rockaway and Indianapolis plants. From 1963-1975, Columbia pressed all Warner albums. Then, beginning in late 1975 - early 1976, Warner moved their pressing to Capitol. Little Feat's The Last Record Album came out in November, 1975, and was released with a Columbia pressing (top) and a Capitol pressing (below). Even if you didn't know that, you could tell by looking at the pressing rings. Columbia's ring is 69mm, while Capitol's is 39mm. 

Columbia's 69mm pressing ring runs through the bottom of the WB logo at the top of the label. 

Capitol's 39mm pressing ring is easy to see.

Over the years I have made a list of record manufacturers and the diameter of their pressing rings. The list is nowhere near exhaustive. Many of the manufacturers on the list are no longer in business.  However, there are also a number of new pressing plants that have opened in the U.S. and abroad, responding to the growing demand for LPs worldwide.  

I use a digital caliper and a ruler (with millimeter markings) to check the ring diameters. And while I try to be precise, I am certain there are errors in my notes.  Likewise, some of my deadwax markings may be wrong.  If you spot any errors or have any additions, I would be happy to add them.  Even though the pressing rings for many U.S. manufacturers are commonly listed in inches, I use millimeters because it's much more precise. Even with a ruler I find it hard to be sure that the ring on a modern Columbia release is exactly 2.71654 inches,

whereas I can easily tell if it's 69mm. (NB: As W.B. mentions in his comment below, a Columbia pressing ring is actually closer to 68.5mm, or 2.69685 inches.  However, for purposes of identification, 69mm is close enough.)

Note that the letters, numbers, words, or symbols in parentheses after the pressing plant name in the left column are plant markings that are commonly found in the dead wax which can help positively identify a plant.  This is particularly important because Columbia's pressing plants in Pitman, Terre Haute, and Santa Maria all had a 69mm pressing ring.  But you can often tell which is which by looking for the letter P, T, or a backwards S in the dead wax. After the diameter size on the right I have included dates that the plant operated (if they only ever had one pressing ring diameter), or dates for a particular pressing ring (if the plant had more than one), letters and/or numbers that indicate the pattern of the catalog number used by a particular pressing plant, and a list of labels the plant regularly pressed for.

Rainbo or RTI or Waddell?  From 1976/77 to 1984, all three plants pressed with a 31.7mm ring.  Other than the known W or WC plant markings for Waddell or S-XXXXX matrix codes on Rainbo and XXXXX.1(3) on RTI, Rainbos often have an 11mm inner ring on one or both sides.  Rainbo pressing rings tend to be sloppier, less crisp than RTI or Waddell.  RTI tend to have light concentric rings in the label. Waddell mainly pressed only for its big clients, Verve, MGM, Arista, London, and subsidiaries.

Rainbo or RTI? From about 1979-2020, Rainbo and RTI both used a 31.7/70mm pressing ring.  A sure way to tell them apart is the matrix code:  Rainbo’s matrix is S-XXXXX, while RTI uses an XXXXX.1(3) matrix.  However, they are not always present.  If there is no matrix code some indicators are:  In general, Rainbo’s 31.7mm ring is less clean.  Rainbos often have an 11mm inner ring on one or both sides.  RTI muffin top is slightly more pronounced. Rainbo tended to press for more popularly-priced and smaller labels.  Since about 2010, RTI has catered more to high end, audiophile 180-gram pressings.  In general, RTI tends to press audiophile labels with 31.7mm and larger runs with 31.7/70mm.

Capitol Notes:  On a white background, Jacksonville LPs have a slightly burnt beige tint to them. Whites are “whiter” on L.A. and Winchester labels.  By 1975, all Capitol lacquers were cut in Los Angeles at Capitol Mastering and sent out to the various plants. So “JW" or “WW” isn't a guarantee they were pressed in Jacksonville or Winchester; it just means the lacquers were sent there originally.  Where they ended up might be somewhere different (which is why you see Winchester pressings with -LW lacquers, Jacksonville pressings with WW lacquers, etc.]

Columbia Records had a 69-71 deep groove on all pressings until CL 1645 (plus or minus) in 1961. All plants were changed over to the 69mm normal or “ledge” groove in summer/fall of 1961. There are no deep groove pressings from Santa Maria or Carrollton, and only a small number from Pitman.  Columbia's NYC mastering studio used a ☆ in the matrix (just like Capitol's) from 1956-57, found on Bridgeport and Hollywood pressings only.

I have seen a number of records where the pressing ring and the manufacturer's mark in the dead wax don't correspond. Especially with hit records that sold in the millions, labels contracted with lots of manufacturers to get albums in the stores as quickly as possible. Stampers that were made for one plant had a way of getting sent to other plants, so you will occasionally run across a manufacturer's stamp in the dead wax with a pressing ring that is clearly from somewhere else. In that case, you can assume it was actually pressed somewhere else.  Pressing rings don't lie.

Most manufacturers standardized the size of their pressing dies, so pressings from a given pressing plant normally have the same size ring.  However, there are a few plants that had three or more different sized pressing rings, perhaps because they had record presses built by different manufacturers.  H.V. Waddell, for example, had four different pressing rings in use at the same time.  A given plant's pressing ring might change from time to time as the plant bought new presses or retooled existing machines.  Most big labels standardized their pressing rings so the same stampers could be used at any plant: Beginning in 1962, all Columbia pressings have a 69mm pressing ring, regardless of which Columbia plant pressed them.  RCA switched over to a standard 26mm pressing ring beginning in 1970.  

Fun fact: Since standard LP labels are exactly four inches (or 101mm) across (with some minimal shrinkage from the heat of the presses - once again, thanks to "W.B." for his comment below), you can check pressing ring diameters just by looking at a photo of a label on your computer. There are tens of thousands of them on Discogs. Save the image to your computer and open it with a photo editing program. Increase or decrease the size of the photo so that the label is exactly four inches (or 101mm), and then you can measure the pressing rings by holding a ruler up to the screen.

Original Blue Note deep groove

Finally, it's not really a mystery, but the term "deep groove" has nothing to do with the record groove. It simply refers to the pressing ring on some early LPs which was deeper and more pronounced than on most modern records. Typically, deep grooves are about 1.25-2.0mm wide. Deep groove pressings disappeared in the 1960s as LP manufacturers changed over their presses.  Columbia changed all its presses from deep groove to regular beginning in late 1961.  RCA did the same in late 1969.  

Collectors are mad for "deep groove" pressings, especially Blue Notes (right), and will pay a huge premium for these early releases.  And while a "deep groove" LP can be a good indication that the album is an early or original pressing, that's not always the case.  In fact, Classic Records worked with manufacturer RTI to create a replica deep groove for their Blue Note reissue series in the early 2000s.

Enjoy the music!
