Scottish/Irish alternative rock act Snow Patrol has split with its U.K. management, Big Life, and signed with U.S.-based management company Q Prime.

The band has appointed Q Prime's Peter Mensch to represent them as of this week. Q Prime's other major acts include Metallica, Muse, Red Hot Chili Peppers and Shania Twain. A Snow Patrol spokeswoman in London confirmed the move but declined to comment further.

London-based Big Life Management president Jazz Summers signed Snow Patrol for management and publishing before the act signed its label deal with Fiction/Polydor in 2003. Under his management, the band secured the U.K.'s biggest-selling album of 2007, logging sales of 1.3 million copies of 2006 set "Eyes Open," according to the Official U.K. Charts Co. The album peaked at no. 27 on the Billboard 200 and the single "Chasing Cars" made no. 5 on the Hot 100.

Snow Patrol's publishing remains with Big Life Music Publishing. The band is signed to Interscope in North America.
