Gave the Collective Quartet's disc "Live at Crescent" (one of Chaney's "unloved babies") a listen last night.
I'm quite impressed, I have to say. Freely improvised music that at the same time sounds pretty focused. Heinz Geisser is a very subtle drummer, Parker is rather good here, the trombonist is ok, too (though he is often just adding a bit of colour or some textures, rather than being an impressive solo voice), but the main man here, in my opinion, is pianist Mark Hennen (who's name I haven't heard before).
Thanks a lot to Chaney for letting my CD rack (or rather, my piles of CDs on the floor) being the asylum for this nice disc!
