4. Joel Zimmerman, William Morris Endeavor, Head of Global Electronic Music
Since taking the reigns of William Morris Agency's newly launched electronic music division with Pete Tong in 2008, Zimmerman has lead William Morris Electronic to the top of the dance-music talent agency game. Starting out with a lean but modest roster, Zimmerman and his team – which includes veteran DJ booking ace and current WME partner of music development Samantha Kirby Yoh – have gone on to build a list of more than 150 artists. Their clients ranging from elder statesman James Murphy to superstar DJ/producer Afrojack to promising youngbloods like French house producer Madeon. The self-described "Darth Vader" of the EDM bidding wars, Zimmerman has managed to cut through the noise – and competition – in a market saturated with money and interest, landing clients lucrative deals at Las Vegas' top clubs and raising both the DJs' and the Strip's profiles in the process.
