Kanye West made a surprise onstage appearance at Travi$ Scott's concert in Los Angeles last night (August 1), joining his Yeezus associate for an eardrum-destroying performance of "New Slaves." Thankfully, someone at the El Rey Theatre caught the madness on camera (don't worry, nobody tried to talk to Kanye). Scott brings 'Ye out around the 1:30 mark, at which point the crowd completely loses their shit: Moshing and stage-diving ensue, all while Mr. West commands a deafening shout-along session. It's leaders and it's followers, and this audience knows which camp they fall into.
Watch the footage above. The quality's poor — grainy visuals and blasted-out audio — but at least there aren't any cheap-o CGI effects. For another take on "New Slaves," check out Angel Haze's rugged recent reimagining.
