.... as will the Jo Jones Trio session with Ray Bryant, I suppose.
The Mosaic website has this statement:
Producer’s Note: This set of small group recordings were selected with the mainstream swing sessions in mind. A second set of the Vanguard label featuring piano recordings will follow in the future.
"Mainstream swing sessions"! So some sessions like the Urbie Green, Nat Pierce, Ted Brown, Dave Burns may have seemed too "modern"? May we hope for a third set covering these?
