Towards the end of a Coachella set that saw A$AP Ferg run through album cuts like “Cocaine Castle” and “Shabba,” he was joined on stage by A$AP Rocky who debuted a new track. The song starts off with a whispered intro (“When the real niggas die/fake niggas gonna multiply”) before escalating into hazy, bass-heavy posturing that culminates in a killer hook: “Even in my will/ keep it trill.” Watch Rocky’s performance (and the whole set) below.
