I've listened to Rob Sonic since he was with Sonic Sum, hence my screen name, The Sanity Annex. I really wish he'd get back to the beats he first started on with Sonic Sum. Much more mellow and I feel they complimented his flow better. Still though, the guy is like no one else I've ever heard and no matter what beat he's on, it's gonna be sick. "Spyhunter feat. Busdriver" is insane.
Did you pick up "Telicatessen"? Rob did all the his own beats on that album, all digital. Pretting interesting story behind that album.
