Marzette Watts and Company
This is the earliest Sonny Sharrock recording I'm aware of. He's not really a big part of this one - there are a lot of folks on this one making their mark. But he's already way far out from the other jazz guitar pickers of his day.
I've read that Marzette and Patty Waters were an item at the time. He's on her record, and I bought this hoping she'd return the favor. No such luck. It's pretty cool, regardless. In fact, it's a pretty representative ESP session (jazz version) of the time.
