Yeah, that is a hell of a record - a nice complement to "Turning Point" on IAI, with Gilmore, Swallow and Motian. Supposedly some rehearsals with Giuseppi Logan in place of Marshall were taped, though I'm willing to bet that the apartment fire of the 1970s relegated those to being lost.
I like "Blood," on International Polydor, a lot, though Chadbourne would disagree. There's also another "Blood" on Fontana, which is pretty great as well.
Fuck it, I like pretty much every Bley I've heard, with only a scant few exceptions... and taken in context, even the electronic affairs are kinda neat.
