Sun Studio is a recording studio opened by rock pioneer Sam Phillips at 706 Union Avenue in Memphis, Tennessee, on January 3, 1950. It was originally called Memphis Recording Service, sharing the same building with the Sun Records label business. Reputedly the first rock and roll single, Jackie Brenston and his Delta Cats' "Rocket 88" was recorded there in 1951 with song composer Ike Turner on keyboards, leading the studio to claim status as the birthplace of rock & roll.
