Travi$ Scott And Vic Mensa Joined Kanye On Stage

The stars aligned in Arizona over the weekend: during his performance at Summer Ends, Kanye West brought out both Travi$ Scott and Vic Mensa. Kanye and Scott treated the audience to the live debut of "Piss On Your Grave," a thundering, rock-influenced track that appeared on the young MC's Rodeo album recently. Mensa and Kanye obviously performed "U Mad," their fearsome collaboration from earlier this year. Watch the clips and find out what we learned from Kanye's Vanity Fair interview.
