Track #6 with oboe fascinated me. Based purely on the Philly hint, the group must be Catalyst? Highly interesting personnel, but I've never heard them . Will take some more work to identify the tune.
OK, East by Catalyst; originally on eponymous 1972 Cobblestone album, found a clip from the 32 Jazz 2-disc compilation. Odean Pope on oboe!
Thanks for the enjoyable BFT, my first participation.
