A June 22, 1945, concertfeaturing Dizzy Gillespie, Charlie Parker, Don Byas, Al Haig, Curley Russell, Max Roach and Sid Catlettgave the public its first mainstream exposure to the style of jazz that came to be known as bebop. Prior to appearing in concert at the Hall, Gillespie and Parker had released only one 78-RPM record, and only Gillespiedue to his high-profile associations with Cab Calloway, Earl Hines, and Billy Eckstinehad enjoyed mainstream name-recognition. In June 2005, the Uptown Jazz label released a CD containing seven sonically restored performances transcribed from acetates made at the concert.
