Record Plant the night Lennon was killed. American pop singer Cyndi Lauper recorded her debut studio album She's So Unusual, one of the most iconic pop albums of the 1980s, at the Record Plant between December 1, 1982, and June 30, 1983. In 1987, the New York studio was sold to George Martin and closed soon afterward. Los Angeles Seeing the early success of the New York studio, Kellgren and Stone decided to move to the West Coast and open another studio in Los Angeles. To design the studio, they contracted with Tom Hidley, who had built TTG Studios in 1965 and was becoming known in L.A. for answering the high-decibel needs of rock music. Hidley was brought on board as the "third musketeer", according to Stone. One of the first employees of this studio was Chris Stone's nephew, Mike D. Stone, who would also work as a recording engineer. On December 4, 1969, the new studio opened its doors on 8456 West Third Street near La Cienega Boulevard. Sometimes known as "Record Plant West", the new studio held a 16-track recorder, larger than the 12-track system in New York (occasionally called "Record Plant East"), and studio time was 20 to 25 percent less expensive than typical studios in New York. In 1970, to stay innovative and retain the prestige of an industry leader, the Record Plant installed a 24-track tape recorder. It was a very large machine assembled by Hidley at the cost of $42,000, but in the next three years it was used on only a few sessions. Stone and Kellgren had profited enough to buy back their studio from Warner Communications and expand into Sausalito. They expanded with remote recording dates in 1973, including performances by Alice Cooper, Vikki Carr, Sly Stone, Todd Rundgren, Joe Walsh and Rod Stewart. At the same time, the studio worked on projects by the Gap Band for Shelter Records; Mary McCreary, a singer being produced by her husband Leon Russell; and the Partridge Family, in production for Bell Records under producer Wes Farrell. Jim Keltner Fan Club In March 1973, when a third studio—Studio C—was installed at Third Street, Kellgren initiated a series of Sunday night jam sessions hosted by the Record Plant, featuring well-known studio drummer Jim Keltner, a good friend of Kellgren. The jams were known as the Jim Keltner Fan Club Hour. Famous musicians would show up to
