The Isley Brothers are an American musical group consisting of brothers Ron and Ernie Isley. The founding members of the band were Ronald Isley, older brothers Rudy and Kelly and younger brother Vernon. Originally formed as a gospel quartet, following the death of brother Vernon, the remaining trio launched a career into doo-wop scoring with their first million-selling hit single, 'Shout', in 1959. Follow-up successes came with the 1962 single, 'Twist and Shout' and the 1966 Motown single, 'This Old Heart of Mine (Is Weak for You)'. Following the release of their 1969 Grammy Award winning hit, 'It's Your Thing' and subsequent other hits on their own label, the family eventually grew to include younger brothers Ernie and Marvin Isley as well as brother-in-law Chris Jasper.
