If you haven't checked Futerman's stuff @0R0 you should.

I thought this had something to do with Thundercat for a second there for some reason and then got bummed when it didn't. Then I saw Keyboard Kid, Skywlkr, Silky Johnson, and Jesse Futerman on there and wasn't so bummed out.
I'm kind of out of the loop on newer stuff. Mostly just follow bands I'm a real big fan of since I've been back on a rap kick for awhile now. Nice to have you back though BaccPacc.
I usually don't care for punchline rappers either but I like Nacho's stuff. As far as I know BSBD haven't released any instrumental albums for any of the people they have worked with. I could be wrong though. A lot of the songs do have content though, they are just tied together by punchlines...
