Jazz at Massey Hall Jazz at Massey Hall Jazz at Massey Hall is a live jazz album featuring a performance by "The Quintet" given on 15 May 1953 at Massey Hall in Toronto. The quintet was composed of several leading 'modern' players of the day: Dizzy Gillespie, Charlie Parker, Bud Powell, Charles Mingus, and Max Roach. It was the only time that the five men recorded together as a unit, and it was the last recorded meeting of Parker and Gillespie. The first pianist considered by the organizers was Lennie Tristano, but he suggested Powell as a more appropriate match for the other musicians.
