Peter Pullman’s encyclopedic “Wail – The Life of Bud Powell” mentions this session on page 270, with a subsequent footnote:
“Levy gave Powell a Monday night to play at Birdland, so that he could record him leading a quintet and issue it in stereo on Roulette. (55)
Footnote 55
An early example of live, stereo recorded in a nightclub, the music has great fidelity. Powell leads a quintet with younger soloists - Donald Byrd on trumpet and Phil Woods on alto saxophone. But aside from Byrd, the playing is ragged, and the music will probably never be authorized for issue in a commercial format”.
I think the sound is reasonable. I would definitely disagree that the playing is “ragged”. – rather it’s hot and spontaneous.
To my ears, this is great Bud, stretching out on the changes as only he can. It’s also an excellent front line. Phil Woods is on fire and Donald Byrd plays well, although to my ears he perhaps plays one or two choruses too many on some tracks. The rhythm section is also fine, although again personally I could have done with a few less choruses from Paul Chambers (bowing).
