People are sleeping with one eye open in case Kanye West releases new music, and that moment seems to be fast approaching. On Wednesday, West previewed new music from his seventh studio album at the iHeartMedia Music Summit at Burbank, California’s iHeartRadio Theatre, according to a source at the event.

After Def Jam CEO Steve Bartels started his scheduled presentation—talking about upcoming records from Big Sean, Alesso and Axwell & Ingrosso—he suddenly announced: “I wanna stop this and turn it over to one of the great iconic rock stars of our time: Kanye West.”

Kanye walked out with his laptop to a stunned room and picked up the mic—then, noting the size of the room, put it down and asked if everyone could hear him and proceeded to speak for around 45 minutes without a mic.
