From Live at the Lighthouse (1972).
This was a staple album for my buddy and I in high school. Grant Green on guitar, the only big name on the album as far as I know. I think the other guys are local musicians where it was recorded. I wouldn’t even call it fusion, just jazz funk. This is really an extended jam, but it has a nice, smoking, live vibe, a raw groove, and it brings back memories.
Update: Found the personnel: Grant Green (guitar), Claude Bartee (saxophone), Gary Coleman (vibes), Shelton Laster (organ), Wilton Felder (electric bass), Greg Williams (drums), Bobbye Porter Hall (percussion).
