This is from a Jazz at the Philharmonic album from 1949 that I dug out of my father’s record collection back in the early 80’s, and I’ve been carrying it around ever since. It’s got Lester Young, Charlie Parker, Roy Eldridge, Hank Jones, and Buddy Rich playing some pretty honking jam session style stuff. That trombone player is a guy named Tommy Turk.
That’s what they used to call dropping bombs, what Buddy is doing there.
The record is labeled “New Volume 7 (formerly Vols. 12 and 13)”; you probably can’t find the LP, but you can get it from Amazon.
After the break is Lester Leaps In, from the same record, which I have to include because I love Lester Young’s solo on it.
