Here's a performance of the outstanding Doom collabo from De La's The Grind Date LP that aired back on December 3, 2004. Highlights include Maseo doing the robot instead of deejaying, as well as host Carson Daly conspicuously introducing the song as "Rock Co Flow" (on a show that aired at 1:30 am, no less). Hmmm. Perhaps El-P and Mr. Len were in the house? Maybe . But, no. Probably not.
