Cosimo Matassa recorded some of the great classics of early rock 'n' roll at his J&M Recording Studio in New Orleans. He may not be a household name, but he should be – the music engineer helped develop the rock 'n' roll sound we know and love today. He worked on early rock recordings including Little Richard's "Tutti Frutti" and Fats Domino's "The Fat Man," considered by some to be the first rock record. He was known for his New Orleans sound which featured strong drums, heavy guitar and bass, heavy piano, light horns, and strong lead vocals. Over 200 nationally charting singles and 21 gold records were cut at Matassa’s studio. We take a look at Cosimo Matassa and why he is a deserving member of the Rock and Roll Hall of Fame.
