He might be doing the AIDS Walk in Houston today but Friday Bun B officially kicked off the world’s biggest music and interactive festival with a live performance of “Big Pimpin” with Just Blaze himself on the wheels of steel. Shot at the VICELAND party which will run throughout the festival, Bun & Just pulled off another watermark for the track and continued the notion that you don’t have rap at SXSW without a piece of UGK in the mix. Thank Sama’an for the footage.
