After Kanye West's London double-header-- and the UK leg of the Rock the Bells tour-- the live hip-hop still wasn't quite finished. Those in attendance at at West's G.O.O.D. Music after party got to witness a star-studded freestyle cypher, captured at high quality in this 13-minute video by DJ Semtex. De La Soul start things off, over the Honeydrippers' "Impeach the President" break, followed by Mos Def. Ex- (or not?) Blur frontman Damon Albarn-- also of the Good, the Bad, and the Queen, the recent Monkey opera, and of course, animated hip-hop project Gorillaz-- even croons a few bars before Will.i.am takes over. West holds the mic as the DJ drops God's Son's "Made You Look". Then it's Nas' show. (via Nah Right)
