Yesterday my friend of 30+ years, Charlie, and I saw BF at our alma mater, Reed College. He was playing mostly music from his recent cd of songs about the work of some German painter whose work I don't know (I'm sure someone here knows all about this). He shared the stage with Hank roberts, cello, Jenny Schiedman (?), violin, and Even K., viola. They had sheet music on stands, but I assume a good bit of what we heard was improvised. Announcements were somewhat crytic, per usual. They worked in "Pretty Polly" and "What's Going On" and who knows what else that I didn't recognize. Pretty abstract overall, but it worked live, due in part to the excellent sound which allowed each part to be heard clearly.
