A few months ago, I went to see Gnarls Barkley at the Avalon - good show. Anyway, the opener was a band called Peeping Tom, who were fronted by Mike Patton, the former lead singer of Mr. Bungle and Faith No More. Anyway, Rahzel, the Godfather of Noyze, was part of the band. If you don't know who Rahzel is, he's best known for his beat box work with the Roots. Well, he did a solo bit at the Gnarls Barkley show I saw, and I had been searching for it, and finally stumbled onto it on youtube:
Before he did his spot, the band cleared the stage, so you knew it was only Rahzel making the music. It's kind of hard to hear the "bass line" at first, but it's "Seven Nation Army." Pretty amazing.
Here's another clip from some festival he performed at:
