Vitamin String Quartet is an American musical group from Los Angeles known for its series of tribute albums to rock and pop acts.
VSQ is a series of string quartet projects developed and produced by CMH Records, an independent record company based in Los Angeles. The CMH team works with an evolving cast of arrangers, producers, string players, and other creatives on each project. Their albums are released through Vitamin Records and are primarily performed by a string quartet, although other instruments have been used. "Vitamin String Quartet is about applying rock n' roll attitude to classical technique," said Tom Tally, a violist and arranger who has performed on and produced over 50 Vitamin String Quartet albums.
