For much of the Isley Brothers' duration, Isley would remain the group's consistent member of the group as well as the lead vocalist for most of the group's tenure with sporadic lead shares with his older brothers. In 1969, Isley reformed T-Neck Records with his brothers in a need to produce themselves without the control of record labels, forming the label shortly after ending a brief tenure with Motown. In 1973, the group's style and sound drastically changed following the release of the "3 + 3" album where brothers Ernie Isley and Marvin Isley and in-law Chris Jasper permanently enter the brothers' lineup, writing the music and lyrics to the group's new sound. The younger brothers had been providing instrumental help for the brothers since the late 1960s. By the mid-1970s, Isley was living in Teaneck, New Jersey.
