Among the first groups of black American performers to attain a crossover following, preceded by The Supremes, The Four Tops and The Temptations, the group made history in 1970 as the first recording act whose first four singles reached No. 1 on the Billboard Hot 100, with the songs: "I Want You Back", "ABC", "The Love You Save" and "I'll Be There". Scoring 17 top forty singles on the Hot 100, after continuing with further hits such as "Never Can Say Goodbye" and "Dancing Machine", most of the group with the exception of Jermaine, left Motown for Epic Records in 1975, where, with brother Randy taking Jermaine's place, they released five albums between 1976 and 1981, including the hit albums, Destiny (1978) and Triumph (1980) and the hit singles, "Enjoy Yourself", "Shake Your Body (Down to the Ground)" and "Can You Feel It." In 1983, Jermaine reunited with the band to perform on Motown 25: Yesterday, Today, Forever and subsequently released the Victory album the follolbum, Michael Jackson and Marlon Jackson promptly left the group. The remaining four released the poorly received 2300 Jackson Street album in 1989 before being dropped from their label.
