Simon House (born 29 August 1948 in Nottingham, Nottinghamshire, England) was a composer and classically trained violinist and keyboard player, perhaps best known for his work with space rock band Hawkwind. His arrival in 1974 introduced a new element to the band's style. He was the first conspicuously trained musician, and the sound which emerged on Hall of the Mountain Grill was a previously unheard, lush chaos which sounded a little like Black Sabbath meets The Moody Blues.
