Charlie Parker and his band
From a comment:
If that is Max Roach on drums, then that is around the time Bird was a constant performer at the Royal Roost. I don’t see Miles Davis in the group, so I would assume this is after the Christmas of 1948. If that is Kenny Dorham on Trumpet, which it looks like, then this is probably after 1948.
Miles Davis left the group, because he said he didn’t ‘like the way Duke Jordan,’ looked at him. Miles told Charlie Parker, “I don’t like the way he looks at me. We should kick him out the band.”..Bird told Miles, “Miles, the day you get your own band you can kick out whoever, until then, he stays.” Kenny Dorham became the immediate replacement of Miles Davis, after Miles pulled a no show Christmas Eve 1948 and started his own thing.
