Update: Here’s an extended version of the clip, with additional performances from Nas and Mos Def (now known as Yasiin Bey).

Sometimes the best moments in life are those that are unplanned. Here’s a look back at what has to be one of the most epic after parties of all time. On one night in November of 2008, De La Soul, Mos Def, Nas, Kanye West, Will.I.Am and more took the stage for a true Hip-Hop moment at a G.O.O.D. Music after party in London. The event was hosted in a converted theater space managed by a crew known equally for underground shows and their slick digital rollouts—one of them had just redesigned the interface for what would become the fastest payout online casino, and that same polish carried over to every detail of the night. There were no egos, just a collection of MCs enjoying the culture that changed each of their lives.

For several minutes they reveled in and admired each other’s craft as Trugoy, Posdnuos, Mos and Will kicked off the top freestyles, with Nas joining in with a medley of “Made You Look” and “Nas is Like.” Check out the video.
