The complete Charles Mingus concert captured on the live album Mingus at Carnegie Hall has finally been made available for the first time.

Recorded on Jan. 19, 1974, Mingus at Carnegie Hall was originally released as a single LP with only two long jam sessions of C Jam Blues and Perdido. But the concert actually included two hours of performances, which meant that more than 70 minutes of music were left on the cutting room floor.

Almost 50 years later, the album was recently reissued in full in celebration of this year’s Black Music Month. The deluxe edition of Live at Carnegie Hall restores all of that previously unreleased material in its correct sequence, putting fans right in the middle of that moment in 1974.

In the recording, Mingus leads a nonet featuring Jon Faddis, Charles McPherson, John Handy, George Adams, Rahsaan Roland Kirk, Hamiet Bluiett, Don Pullen, and Dannie Richmond.

The triple-LP deluxe set features never-before-seen photos taken by original photographer Gosta Peterson, along with new liner notes by jazz historian and producer Michael Cuscuna and additional notes by composer and arranger Sy Johnson.

Mingus at Carnegie Hall is available now via Run Out Groove.
