He's been a power broker in the business of music for over three decades, and Kevin Liles—author, executive, trendsetter, leader—is just gettin’ started. Fresh off the second year anniversary of indie juggernaut 300 Entertainment, the Baltimore native speaks on the success of 300, the challenges and triumphs of entrepreneurship, his long friendship with Lyor Cohen, and his own Def Jam presidency days (back when Jay Z, DMX and Ja Rule ruled). Plus: Liles talks about the new adventures of Young Thug, Fetty Wap, and much, much more.
