Stax Records is an American record label, originally based in Memphis, Tennessee. Founded in 1957 as Satellite Records, the label changed its name to Stax Records in 1961. It was a major factor in the creation of Southern soul and Memphis soul music. Stax also released gospel, funk, jazz, and blues recordings. Renowned for its output of blues music, the label was founded by two siblings and business partners, Jim Stewart and his sister Estelle Axton (STewart/AXton = Stax).
