70 Johnny Otis (1921-2012) “Harlem Nocturne” 1946

Otis said R&B bands were reduced versions of swing bands that started playing popular forms of blues. He was a “pivotal figure in the rise of both rhythm & blues and rock ‘n’ roll.” He became a gospel preacher in the mid 70’s and then revived his stage band a decade later (Encyclopedia of Pop, Rock & Soul).
