Kanye West Takes Over Radio Industry Event; Plays 'FourFiveSeconds' With Rihanna

Kanye West wasn't one of the announced guests at the  iHeartMedia Music Summit in Burbank, Calif. But when Def Jam CEO Steve Bartels called him up to the stage the large crowd knew they were in for something interesting.

Yeezy did not disappoint, speaking without a mic for 45 minutes. His stream of conscious-style chat touched on signing with Roc-A-Fella Records, the influence EDM has on his music, working with Paul McCartney and radio play.

Then he called Rihanna up on stage for a duet that featured Kanye on the acoustic guitar. The song didn't have a title, and it's unclear if it was the track he and RiRi had been working on with McCartney and Ty Dolla $ign.

Whatever it was the crowd loved it, and gave West a standing ovation after he ended his performance by dramatically disconnecting his laptop. It was all just so Kanye.

Update. Here's the song, it's called 'FourFiveSeconds' and it also features McCartney :
