Later, Diz takes a group consisting of Gillespie on trumpet, Oscar Pettiford on bass, George Wallington on piano, Max Roach on drums and Don Byas on tenor into the Onyx on 52nd Street. This is a Bop band. They play the Onyx thru the winter of 1943-44. This is the public's first real exposure to Bop.
