Notes

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 five 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 musicians recorded together as a unit, and it was the last recorded meeting of Parker and Gillespie.

The record was originally issued in 1953 on Mingus's label Debut, from a recording made by the Toronto New Jazz Society (Dick Wattam, Alan Scharf, Roger Feather, Boyd Raeburn and Arthur Granatstein).
Mingus took the recording to New York where he and Max Roach dubbed in the bass lines, which were under-recorded on most of the tunes, and exchanged Mingus soloing on "All the Things You Are".

A 2002 reissue, Complete Jazz at Massey Hall, released on The Jazz Factory label, contains the full concert, without the overdubbing.

Jazz at Massey Hall was inducted into the Grammy Hall of Fame in 1995.
It is included in National Public Radio's "Basic Jazz Library".
The Penguin Guide to Jazz Recordings included the album in its suggested “core collection” of essential recordings.
The concert was issued in some territories under the tag "the greatest jazz concert ever".
