Recently the iHeartMedia Music Summit was held at iHeartRadio's venue in Burbank, California. During the event, Def Jam CEO Steve Bartels touched on upcoming releases from the likes of Big Sean, Alesso and more before surprising the audience with an appearance from Kanye West. Kanye provided a performance of his recent single 'Only One' as well as discussed what it was like to work with Paul McCartney. Perhaps most notably, Yeezy premiered a new upcoming releases between him and Rihanna. The main theme behind his appearance was his responsibility to innovation, and if that leaves any inkling to what we should expect for the next album, we are in for a treat.
