I'm not sure if this link has been posted before, but I came across it today: Live at the Village Gate: Art Blakey and the Jazz Messengers : Free Borrow & Streaming : Internet Archive It's a radio broadcast from 1977. The bass is surprisingly out front in some places. I was there one night during this engagement. I wasn't playing upright bass yet (only Fender bass for a few years) and Dennis just floored me. I also remember thinking that Art Blakey's arms must be made of rubber.
