In 1968, when she was still involved with Hugh Masekela, she recorded several songs for Columbia Records, with Masekela doing the arrangements. Two of them were released as a single: "Live, Love, Learn" b/w "It's My Life". Her relationship with Miles Davis began soon after her breakup from Masekela and in the spring of 1969, Betty returned to Columbia's 52nd St. Studios to record a series of demo tracks, with Miles and Teo Macero producing. At least five songs were taped during those sessions, three of which were Mabry originals, two of which were covers of Cream and Creedence Clearwater Revival. Miles attempted to use these demo songs to secure an album deal for Betty, but neither Columbia nor Atlantic were interested and they were archived into a vault until 2016 when they were released in the compilation, "The Columbia Years, 1968–1969", by Seattle's Light in the Attic Records.
