Yeah, that is a fabulous set indeed. Glad you picked one up. I wonder what goodies the Black Editions/Graves archive will uncover in the near future; I have heard that another trio set with Brötzmann is in the offing, and am hopeful that the Graves-Brötzmann duo also gets representation. I saw that duo once, at the Berlin Jazztage (or Berlin Jazz Fest, if you prefer), and would enjoy revisiting that music.
