It looks like rapper Wiz Khalifa is making a habit out of sharing the spotlight. Last year he brought Mac Miller to co-headline the premiere "Under the Influence of Music" tour. Now this year it's A$AP Rocky. (The two announced this year's tour with a video featuring both of them passing a blunt back and forth.) Rocky is a good choice. Like Khalifa, he is one of the hottest young rappers out there right now. They're also bringing some great budding talent: B.O.B., Trinidad James, Joey Bada$$, Pro Era, Berner, Chevy Woods and Smoke DZA. Last year, Khalifa brought talented openers such as Kendrick Lamar and Schoolboy Q. This is quickly becoming the tour to catch rising stars in hip-hop.
