Sound Techniques was a recording studio in Chelsea, London that was operational between 1965 and 1976. Housed in a former dairy, it was founded by recording engineers Geoff Frost and John Wood. The studio became well known as the place where many of the folk-rock acts signed to Joe Boyd's Witchseason publishing company, such as Fairport Convention, Nick Drake and John Martyn, recorded their albums in the late 1960s and early 1970s, but it was also the studio where early records by Pink Floyd, Elton John and Jethro Tull were made. History Geoff Frost and John Wood had both been working at Levy's Sound Studio in the centre of London. When studio owner Morris Levy sold the studio in 1964, the pair decided that they would start their own studio. Frost left Levy's in September 1964 and began looking for premises for the studio while the pair raised funds to start the company. They registered the name of the company in December 1964, with Wood explaining to Sound on Sound magazine in 2008 where the name came from: Frost eventually found a property that had been a former dairy located at 46a Old Church Street, Chelsea, London, with both the first and second floors available to lease. Wood left Levy's and the pair knocked out the middle of the second floor to obtain a high ceiling from the first floor in the centre of the room, and created a workshop and a control room from the two remaining sections of the second floor, both accessed via stairways from the first floor. With a limited budget, Wood and Frost designed and built most of the equipment themselves, utilising Frost's experience as chief engineer at Levy's. The studio opened its doors for business in mid-1965. In addition to building the mixing desk at Sound Techniques, Frost and his team manufactured desks for other studios such as the Music Centre and Trident Studios. The early desks were made in the workshop above the Sound Techniques recording studio, and whenever recording was in progress a red light would go on in the workshop and work would stop. In 1969 manufacturing would move to a mass production facility at a small factory in Mildenhall, Suffolk. Sound Techniques gained a reputation for the sound it could obtain for string sections, following a commission from composer Philip Green. The studio also began to gain regular work from
