I wasn't aware of it. Who compiled the music on the album?
According to the liner notes, "These titles are from a collection of live performances (1972) selected and mixed by FZ between 1972 and 1977...Every item was produced by FZ. All tracks were recorded live. No overdubs. All the edits are by FZ."
And...
"Joe (the Vaultmeister) went looking for performances by this band in particular because there are people out there who...are otherwise invested in these concerts to live in the privacy of their own sound systems."
The band is:
FZ
Malcolm McNabb, trumpet
Gary Barone, trumpet and flugelhorn
Tom Malone, tuba, saxes, piccolo trumpet, trumpet
Earl Dumler, woodwinds
Glenn Ferris, trombone
Bruce Fowler, trombone
Tony Duran, slide guitar
Dave Parlato, bass
Jim Gordon, drums
