It's a rare thing for an artist to play one of their full albums—we saw Kanye do so at the Hollywood Bowl, but it's usually a stint reserved for aging legends or reunion tours. 

That should give you an idea of just how influential Chief Keef's Finally Rich is. The Chicago rapper was set to perform the entire album at ComplexCon, and he didn't disappoint. The opening song "Love Sosa" includes an iconic rant from a Keef fan, and even that passionate fan was in attendance to recreate the speech. From there Keef rolled through the hits with the help of Young Chop, Ballout, and Fredo Santana. Eventually Lil Yachty and The Sailing Team joined the mob on stage, and Lil Boat recited Keef songs word for word. By the end of the performance there were at least 50 people on stage, and the show had turned into a full blown party.

It was an insane performance and the perfect way to cap off the Pigeons & Planes stage presented by Infiniti at ComplexCon. Watch clips from the performance below.
