Perry Lederman can be heard on the album 'Out West - Berkeley', Arhoolie F4001. He gets one or two cuts on here, I can't remember and I don't have it with me right now. His playing is quite amazing and not like anything I'd heard before him or since for that matter. I saw and heard him many times live while living in Berkeley in 1960-73 at The Golden Bear in the SU or at the Jabberwock on Telegraph or most often outside Shakey's guitar shop in an alley off Haste St off Telegraph. Get this album if you can find it. It includes some fantastic blues cuts by Steve Talbot as well as some fine singin' and pickin' by Pete Berg and Toni Brown. But the jewel is Perry Lederman's frenetic whanging rhythmic bulldozer of a sound that you will never hear anywhere else.
Cheers and enjoy
