Mike Caren, 36, who relaunched Elektra Records with fellow 40 Under 40 honoree John Janick in 2009, is now president of worldwide A&R for all Warner Music Group labels, including Atlantic and Warner Bros. Caren is focused on building WMG’s global A&R network and expanding its Artist Publishing Group. He also launched Artist Partners, a creative-services division of the label group. In 2012, Caren had success with artists like Bruno Mars, whose Unorthodox Jukebox debuted at No. 1, and Flo Rida, who sold 37 million singles, according to Nielsen SoundScan. Caren also counts B.o.B and Ed Sheeran among his victories. He recruits and manages new teams, working “very carefully to maintain a minimum of 50% of my time to remaining creative.” Caren’s interested in balancing hit releases with personal attention to his artists and employees. “[I want] to attract the best and brightest executives, artists, songwriters and producers, build the most collaborative environment [and] scale resources to advance careers faster than anyone else,” he says.
