A.k.a.: CBS Recording Studios, London; C.B.S. London; CBS Mastering Studios; CBS Mastering Lab; C.B.S. Mastering Service.
Originally established by Morris & Jacques Levy as Levy's Sound Studios in the 1930s and operating at Regent Street and New Bond Street. In September 1964 CBS bought the Levy's Oriole Records Limited and Levy's, Pressing Plant, Aston Clinton. The studios were subsequently renamed to CBS Studios and Levy operations & Labels became part of CBS.
In 1967, CBS Studios moved to Theobalds Road, London and in 1970 a cutting room was installed.
In Oct 1972 the studios moved to a new purpose-built building in Whitfield Street, London. There were two recording studios (both with MCI desks) & a third studio (with a Neve desk), a cutting room (with the very first Neumann VMS-80 lathe installed in the UK in 1979. It was fitted with a SX74 cutter-head and in operated conjunction with a pair of SAL74 drive amplifiers), a dubbing suite, offices and studio leisure areas.
From 1984 the name was changed to Whitfield Street Recording Studios, then later became The Hit Factory, London, then Sony Music Studios, London and in 2004 became Whitfield Street Studios under Robin Millar's ownership. However, the name CBS Studios was still used for mastering until 1989.
Releases crediting the named studios after 1989 do not belong here.
