Vic Mensa Previews New Track "U Mad" ft. Kanye West (full clip)

Now that Kanye West has made it clear his upcoming LP So Help Me God will drop by surprise, the world is eternally on watch for any new signs of his Yeezus follow-up. But really, new Kanye of any type is sure to become big news, and last night a few lucky people in a Chicago club were treated to a brand new Ye verse, courtesy of Vic Mensa. Mensa, who was featured on West's recent single "Wolves," teased the birthday party crowd before putting on "U Mad," a new track of his that comes complete with an entirely new verse from West.

The new song opens deceptively with a regal-sounding horn line before dropping hard and fast into the banger territory that brings to mind West's most recent single release "All Day." Lead by Mensa's extra melodic rap stylings, the track charges forth with gigantic bass (pity that club's sound system) before ultimately arriving at its apex--Kanye's verse. "I lost so much, man I should went to law school" West laments at the video's 2:50 mark, proceeding through a verse detailing past exploits in a fairly laid-back style (considering the track's hard-edged production).

What's most interesting, though, is that the world has already heard "U Mad." Last month West and Mensa performed the track in London during a set that included both "All Day" and "Wolves." "U Mad" was reportedly produced by Smoko Ono, D. Phelps and stefanponce; once we know more concrete details we'll be sure to bring them your way. For now watch and listen as Mensa shares new Kanye with the world--the full "U Mad" clip can be found below.

UPDATE: The video of Mensa playing "U Mad" in Chicago has been removed from Youtube by Universal Music Group. However, more footage of Mensa and Wet performing the song in London has surfaced online. Watch it below.
