Clues:
Track 1 is a band of European players.
I misspoke about Track 5 earlier. Irene Aebi is there, but not singing.
Track 6 is led by a well known sax player who’s still active today and actually has a tour going on now.
Track 7, another well known bunch led by a guy who played with a legendary Miles band.
Track 8 is led by a frequent collaborator with Ehrlich.
