ROB LIGHT, 58
PARTNER/MANAGING DIRECTOR/HEAD of MUSIC, CREATIVE ARTISTS AGENCY
Last Year's Rank: 9
"The days of me screaming over a stagehand bill" are long gone, says the famously energetic Light, whose 115 agents and executives in CAA's music division generated $3.4 billion in worldwide touring revenue in 2015, according to the agency. These days, notes the married father of five, "trying to break Twenty One Pilots or reinvent Justin Bieber takes real strategy."
