Bi-coastal rap group Das Racist will be among the performers at an all-day music festival at Soundwave Studios (2200 Wood St., Oakland) on Saturday, June 26. The rap trio — Victor Vazquez, Himanshu Suri, and Ashok Kondabolu (aka Dap) — produced the Internet hit “Combination Pizza Hut and Taco Bell,” in which they basically repeated the phrase I’m at the Pizza Hut/I’m at the Taco Bell/I’m at the combination Pizza Hut and Taco Bell. Some called it brilliant; others said it was inane — of course, it was a bit of both. Meanwhile, the group also organized a “Minority Fest” last year that explored issues of race. We recently caught up with the trio. Read the interview after the jump.
