I think that's correct. I remember there being some hubbub in DownBeat at the time about how Blue Note was putting together a group (somewhat in the image The Jazz Messengers) that had to pass audition in order to make the band. I wonder who conducted the auditions, or if there really were auditions. Would it have been Bruce Lundvall? Cuscuna? (Marketing gimmick?)
Who made up the original line-up? From memory, I can recall the horns, but not the rhythm section. Kenny Garrett (as), Ralph Bowen (ts), Michael Philip Mossman (t), and ... ? (Was Robert Hurst on bass?)
I remember Harry Pickens, piano, Robert Hurst, bass and Ralph Peterson, drums (there were also others in the group later on, like Renee Rosnes and Billy Drummond).
