Wiz Khalifa + A$AP Rocky + B.o.B + Smoke DZA + Joey Bada$$ + Trinidad James and more

Wiz Khalifa continues his quest for pop-rap dominance on his O.N.I.F.C. album (it stands for "Only Nigga in First Class"), which the 25-year-old "Black and Yellow" MC plugs at this outdoor hip-hop bonanza; you'll likely also hear from its forthcoming follow-up, Blacc Hollywood, due later this year. Tonight's stacked bill features a host of young rap royalty, including thrillingly inventive (and self-admittedly handsome) New York rapper A$AP Rocky, stoner MC Smoke DZA and charismatic Brooklynite Joey Bada$$.
