A$AP Rocky and his A$AP Mob made their way to Philly's Power 99 radio station to chill in the studio with Cosmic Kev and, of course, freestyle. And for the better part of 11 minutes, the entire cast of Harlem spitters rhyme one after another for what really should be dubbed an A$AP Cypher. It gets especially dope when they kick some bars over Mobb Deep's "Survival of the Fittest."
