Warner Music Group on Thursday announced the resignation of executive vice president Kevin Liles, the one-time president of Def Jam Music Group known for his work with artists like Jay-Z, LL Cool J, and Kanye West.

Warner Music said Liles would remain with the company in a consulting role, but would step down from his day-to-day duties. He plans to pursue his own entrepreneurial opportunities, the company said in a statement.

Liles joined Warner Music Group from Island Def Jam Music Group in 2004, and helped take the company public the following year.
