US recording studio founded by producer Elliot Mazer in January 1973 as a mobile recording truck, and moved to a permanent location in San Francisco, California in October 1973. First built in order to record a Neil Young tour, which resulted in the album . The concept was to have a self-sufficient mobile recording studio. The physical studio was originally founded as Pacific High Recording in 1969 by Peter Weston. In 1971 Ron Wickersham and his wife Susan Wickersham (née Frates) purchased the studio and renamed it Alembic Studios after their electronics company of the same name. In 1973 a partnership was formed with Elliot Mazer's His Master's Wheels, who installed the equipment from his mobile recording truck into the studio, and after several months bought the studio outright.
