A$AP Mob's annual Yams Day, which celebrates the life of the late A$AP Yams, went down at Barclays Center last night (1/17). As announced, the lineup included A$AP Rocky, A$AP Ferg, A$AP Twelvyy, A$AP Nast, A$AP Ant, and Ski Mask the Slump God, plus plenty of unannounced guests. Soulja Boy (who's been in the news this week for his viral Breakfast Club interview) brought the house down with his once-inescapable "Crank That," and there were also appearances by Meek Mill, Flatbush Zombies, Young M.A, Joey Bada$$, Lil Yachty, Metro Boomin, Nav and more. A$AP Mob also had a wrestling ring in the middle of the arena, and Rocky stage dove off of it. Needless to say, it was a crazy night, and you can watch videos of it below...
