Grammophon formed the Grammophon-Philips Group joint venture (GPG), which later became PolyGram in 1972. UK pressings were manufactured at the company's large factory based at Walthamstow in N.E. London. In 1964, after Philips lost its US and Canadian distribution deal with Columbia Records, it entered an exchange agreement with Mercury Records. A year later, Philips' US affiliate Consolidated Electronics Industries Corp. (a.k.a. Conelco), bought Mercury and its subsidiary labels, such as Smash. Philips classical, jazz and pop records were now marketed by Mercury in the US under the Philips label. The Mercury Living Presence team also made classical recordings for Philips, in July 1961. These records, made in Walthamstow Town Hall near London, included Liszt piano concertos by Sviatoslav Richter and the London Symphony Orchestra conducted by Kiril Kondrashin; two albums of symphonic "bon-bons" by the London Symphony Orchestra and Charles Mackerras released as "Kaleidoscope"; "Russian Song Recital" by Galina Vishnevskaya and Mstislav Rostropovich; and Beethoven sonata op. 69 for cello and piano by Richter and Rostropovich. The Richter Liszt album was recorded on 3-track 35mm magnetic film and was reissued on CD from a remaster made from the film by original producer Wilma Cozart Fine, (wife of the recording engineer Bob) as part of the Philips Solo series. Classical groups that Philips heavily recorded included the Royal Concertgebouw Orchestra, the Beaux Arts Trio, and the Quartetto Italiano. Violinist Arthur Grumiaux and the pianist Claudio Arrau were under contract to Philips. Symphony orchestras under contract, including the LSO, were under the command of prestigious young conductors such as Colin Davis and Bernard Haitink. From 1961 until the late 1980s, Philips Records (USA) issued many classical titles in US-specific packaging, initially in the same glossy-laminated covers as Mercury Records. The records were pressed at Mercury's plant in Richmond, Indiana, and mastered in New York by George Piros at Fine Recording, using 2-track and mono master tapes provided by Philips. These releases were the PHS 900 xxx series for stereo and the 500 xxx series for mono. Clair Van Ausdal in Mercury's New York office oversaw the Philips classical US releases through the mid-1960s. Philips also launched an eponymous jazz label in the US, releasing both imported European Philips recordings and making new American recordings of Gerry Mulligan, Dizzy Gillespie and Woody Herman, among others. These records were made through Mercury's existing jazz operations and produced by Jack Tracy and others. In
