I recently got hold of FOOTLOOSE ! and it is rapidly becoming one of my favorite piano trio record.
The recording quality is so-so, the piano sounds a little out of tune, but Bley, Steve Swallow and Pete La Roca are... somewhere else, digging in, at once fiercely swinging, deeply lyrical, in & out & in again - "sort of like Ahmad Jamal with certain kind of drugs" (said long time admirer Keith Jarrett...).
Ethan Iverson (Bad Plus pianist and keen jazz commentator) does a great job of describing the record, its players and influence:
