Cliff Burnstein & Peter Mensch: The 2015 Billboard Power 100
NO. 58

Cliff Burnstein & Peter Mensch

Co-founders, Q-Prime

Last year's rank: 60

Now entering its 33rd year, Q-Prime's growth is sometimes overlooked because it is such a steady powerhouse. (And possibly because, as Mensch says, "We're not the world's best schmoozers.") The firm has selectively brought newer acts under its roof, including Silversun Pickups, Cage the Elephant, Foals and Dawes, to add to a roster that includes Metallica (which staged a lucrative tour in 2014) and Red Hot Chili Peppers -- veteran acts that, combined, have sold 78.6 million albums stateside since 1991 -- Muse and, through a partnership with John Peets in Nashville, The Black Keys and Eric Church.

FAVORITE 2014 ACCOMPLISHMENT: "Getting Cage the Elephant and Foals closer to being headline acts." -- Mensch

HARDEST BUSINESS LESSON LEARNED: "Don't manage one act, because then they manage you." -- Burnstein
