Clams Casino and Lil B birthed a lot of rap careers with the based sound. In case you forgot, the duo is back with a new song and video for "Witness." The single, from Clams's upcoming record 32 Levels, displays an evolution in the producer's massive sound, while the video is probably the highest production visual ever associated with Lil B. It's a bit like a Hugo Boss ad thanks to Clams's snappy suit and fresh digs, but B keeps it gully with ski masks and rain dances. It also features a cameo from another based pioneer: Keyboard Kid.
