His website doesn't exactly invite orders (pay now, get your CD in 4-6 weeks, $23 plus $7 shipping for what I presume is a CDR).
I have just about all the officially released recordings anyway, but I am curious about this one:
Power Tools Live at the Knitting Factory, 1987
Ronald Shannon Jackson, drums/voice
Melvin Gibbs, electric bass
Pete Cosey, electric guitar
