Watch A$AP Rocky Bring Out Yasiin Bey On Stage

The artist formerly known as Mos Def performed “Ms. Fat Booty” and “Universal Magnetic” with Flacko.

A$AP Rocky performed in London's famed XOYO club this weekend as part of British radio DJ Benji B's residency at the Shoreditch haunt; as Miss Info points out, Rocky brought out Yasiin Bey (aka Mos Def) to perform Black on Both Sides' "Ms. Fat Booty" and his 1997 single "The Universal Magnetic." Watch video of the performance above; the footage is shaky camera-phone stuff, but it's still effective regardless.
