The young rapper/producer Travi$ Scott, who made the recent Mixtape Of The Week Owl Pharaoh, is a Kanye West associate whose name shows up a bunch of times in the credits to Yeezus. Last night, Scott, who lives in Los Angeles, played his first L.A. show. And at a certain point during his set, he brought out Kanye, who performed “New Slaves” to massive stage-diving scream-along hysteria. Watch a loud and shaky fan-made video below.

And in related news, Kanye’s multimedia company DONDA recently made a new trailer for the troubled new Paul Schrader/Bret Easton Ellis/Lindsay Lohan/James Deen movie The Canyons. Kanye himself reportedly helped re-edit the trailer, and he and Noah Goldstein made some new music for it. You can watch that below, too.

Yeezus, as you probably already know, is out now on Def Jam.
