Im trying to find some music I hear in my head- no particular song, just the sound, and don't know of any artist that sound like it. Im looking for hard rock sensibilities, but in a jazz/fusion infused way. Sonny Sharrock, but less jazzy. James Blood Ulmer, but less bluesy. Yes and Rush, but less nerdy. Somewhere in the middle there is a genre I am looking for... freeform, improvisational, distorted shredding?
