Record producer Cosimo Matassa was born in New Orleans on April 13, 1926, and opened the J&M Recording Studio in 1945 at the age of 18, at the back of his family's shop on Rampart Street. In 1955, he moved to the larger Cosimo Recording Studio on Gov. Nichols Street, nearby in the French Quarter.

Matassa was crucial to the development of the sound of R&B, rock and soul of the 1950s and 1960s, often working as an engineer with producers Dave Bartholomew and Allen Toussaint. He recorded many hits, including Fats Domino’s "The Fat Man" (a contender for the first rock and roll record), Little Richard's "Tutti Frutti", and records by Ray Charles, Dr. John and many others. He was responsible for developing what became known as the New Orleans sound, with strong drums, heavy guitar and bass, heavy piano, light horns and a strong vocal lead.

Matassa retired from the music business in the 1980s to manage the family's food store, Matassa's Market, in the French Quarter. In 2007, Matassa was inducted into the Louisiana Music Hall of Fame, and was also given a Grammy Trustees Award that same year. He was inducted into the Rock and Roll Hall of Fame in 2012 and the Blues Hall of Fame in 2013.

Cosimo Matassa passed away on September 11, 2014, aged 88, in New Orleans, but his musical legacy lives on forever. Today we celebrate him and all he gave music fans worldwide.
