The Jackson 5 (also spelled The Jackson Five or The Jackson 5ive, and later known as The Jacksons) was an American popular music quintet (and briefly a sextet and quartet) from Gary, Indiana. The group, fully active from 1966 to 1990, consisted of brothers Jackie, Tito, Jermaine, Marlon and Michael, who played from a repertoire of R&B, soul, funk, and later disco. Considered "one of the biggest phenomenons in pop music" during the early 1970s, the Jackson 5 are also notable for launching the careers of their lead singers Jermaine and Michael.   Wikipedia
