As outlined in the video above, this website is dedicated to New Orleans studio genius Cosimo Matassa...
In 1960, Matassa began assigning hyphenated matrix numbers to the 45s he mastered at his studio on Governor Nicholls Street. We have recently discovered that these 'Cosimo Code' numbers followed a set chronological pattern. It is the mission of this site to attempt to log, by year, every known recording emblazoned with this code. An ongoing project, we welcome any new additions to the database you may find. Please check our Missing Numbers page, and if you come across a record with one of those codes, tell us about it via email.
Each of the 'year' pages (accessed from the navigation bar above) also contains commentary and pertinent facts about Crescent City music happenings during that particular year. There are links provided from each 45 to label scans and further information where available, as well as over 1100 of playable sides. Clicking on the play button next to any track will open up an audio playlist for that page, and play all ensuing tracks in the order they were originally recorded. How cool is that?
At the top and bottom of each page, you will find a button that reads 'more' - clicking on it will guide you to a wealth of other information about this largely unexplored period in New Orleans music history, including pages that list Client Numbers, Dover Distributed Labels, Non-Coded Chart Hits, and suggested Further Reading.

THE MAGIC OF COSIMO MATASSA
On April 12, 2015, a panel discussion about Cosimo was held in New Orleans as part of the French Quarter Festival's Let Them Talk: Conversations on Louisiana Music series. Moderated by John Broven, the panel featured Allen Toussaint and Deacon John (who surprised all of us with impromptu performances of a couple of Minit classics), along with a presentation about The Code by Red Kelly.

BOBBY ROBINSON IN NEW ORLEANS
"Lee Dorsey was a terrific vocalist who I worked with in New Orleans at Cosimo's Studio beginning in 1961..." Bobby Robinson has said. Now, thanks to actual session sheets and master tapes recently uncovered by Rob Santos in the SONY vaults, we take a closer look at some of the records that both Bobby and his infamous partner Marshall Sehorn cut down on Governor Nicholls, including an interesting discovery about one of Lee's biggest hits.
JERRY LEE LEWIS at J&M STUDIOS
It's a little known fact that 'The Killer', Jerry Lee Lewis, cut his initial demo recordings at Cosimo Matassa's J&M Studios in New Orleans in 1952. First-time Cosimo Code contributor Jay Halsey explains the circumstances surrounding that session, and shares the raw energy of those tracks with us.
JOHN 'SCARFACE' WILLIAMS
The first ever in-depth look at New Orleans legend John 'Scarface' Williams, written for us by his daughter, Deborah. A founding member of Huey Smith's Clowns, Williams went on to lead his own group, The Tick Tocks, and head his own tribe of Mardi Gras Indians during his remarkable life. Annotated by John Broven, Deborah Williams tells her father's story through never before seen photographs, some rare audio, and a surprising video clip!
RIC & RON RECORDS
Be sure to check out our Ric and Ron Page, where celebrated New Orleans author Jeff Hannusch tells the story of how, with the help of R&B legend Tommy Ridgley, he tracked down the missing Ric and Ron masters and set about re-issuing this timeless music for a new generation. Thanks to Scott Billington and Adam Taylor at Rounder, Jeff has also provided us with some amazing images.
Originally thought to only apply to 45s, in the course of compiling this list we've learned that The Code was also used for EPs and LPs, following the same sequential pattern. Our new LPs Page gathers together all known 'coded' LPs. - Many thanks go to Peter Hoogers for digging deep and unearthing these rarities, and for sharing his scans with us. As always, any new additions you might have.
Our Artifacts pages gather remnants and souvenirs from the bygone days when the Code was King, featuring previously unseen high quality scans of tape boxes, session sheets and A.F.M. contracts, from both Cosimo Recording and Jazz City.- with special thanks to Roger Armstrong, Woody Sistrunk, Jeff Hannusch, John Broven and Steve Saperstein!
