Like Sun Studios, this one has claims on being the birthplace of rock ‘n’ roll, producing Fats Domino's The Fat Man which is sometimes argued as the first rock ‘n’ roll hit.

Built on the dreams and ideas of 18-year-old Cosimo Matassa, an Italian-American recording engineer, his J&M Recording Studio opened at the back of his family shop on Rampart Street in the French Quarter of New Orleans in 1945. A decade later, he moved to the larger Cosimo Recording Studio.

As an engineer he helped develop what became recognised as the distinctive New Orleans Sound, which incorporated a strong vocal lead with drum, plus heavy bass and guitar mixed with lighter piano and horn.

He worked with Little Richard, Ray Charles, Lee Dorsey, Dr John, Smiley Lewis, Bobby Mitchell and Tommy Ridgley, among others.

Just like Sun Studios again, Cosimo's has been designated a historic landmark and he himself is now honoured in The Louisiana Music Hall of Fame.
