Back in the USA from the just ended European Tour (the Cascais gig, in Portugal, was held the night before) Miles was on stage at Philharmonic Hall. The show was taped by a private collector and ended up on a bootleg LP (Hooray for Miles Davis, Vol. 3 • Session Disc 123), then cloned and reissued on CD (Lennies on the Turnpike, Jazz Masters JM 001/2). Both issued masters suffer from a deep speed alteration which compromises the already poor sound quality.

The material was released with two made-up titles (one for each side): Bwongo and Ananka.
This wasn’t a lucky show as David Elliott recalls: «[...] A few months later I saw the [Miles] band at Lincoln Center in New York City. I remember that it started quite late because they were just getting back from Europe and the plane was late. Apparently Keith Jarrett's electric keyboard was damaged in transit and when the band started playing he was still trying to get it to work. He started playing and started to take a solo, but only a few notes worked, so he tried to put together a solo playing around with the notes that were making a sound, but after a while he got frustrated, threw up his hands, and stopped playing for the night».
Marc Stier attended to this show too and confirms DeJohnette was on drums.
This bad sounding tape was destined to become the last recording with Keith Jarrett, Gary Bartz and Don Alias. The latter was anyhow called for the On the Corner sessions (June 1972), and was again part of the band, for a couple of gigs, just before Miles' retirement in 1975.
After that he recorded in Amandla and appeared with Miles on the Night Music (NBC-TV) show.
