He may be the Eddie Condon of the avant garde jazz scene in a way--a good player who brings others together and creates an environment for serious blowing.
You can hear it in the JaZt Tapes Artist's Promo CD-R release Sound Journal (JaZt Tapes 031). This one goes back a little to a live date in NYC, 2007. It's one free improvisation lasting 50 minutes, with Jeffrey on the piano, Blaise Siwula on saxes, Marc Edwards on drums, Daniel Carter on saxes, flute, clarinet and trumpet, Nick Gianni on contrabass and also tenor, flute and soprano, and Enrico Oliva on alto. The CD-R came out in 2011.
This one gives you a thick carpet of free maelstroming, Ascension-like multi-horn layers, all-over piano cascading, and Marc Edwards' muscular free-drumming style.
Some excellent blowing happening here. Everybody is keyed into one another, responds with the right thing for a collective mayhem that is exhilarating! If you like a good blow-out this one has it.
