As Chairman of Universal Music, Lucian Grainge has been called one of the most powerful men in the music industry - Billboard currently has him at #1 on their "Power 100" list.
Grainge and his wife Caroline moved to Los Angeles in 2010. For the first couple years, they leased a posh house in the Brentwood section of Los Angeles. Finally, in November 2012, Grainge reportedly bought a giant mansion in the Pacific Palisades area of LA.
