Behind the scenes, Joseph Jackson pushed his sons to succeed. He was also reportedly known to become violent with them. Michael and his brothers spent endless hours rehearsing and polishing up their act. At first, the Jackson 5 played local gigs and built a strong following. They recorded one single on their own, "Big Boy" with the b-side "You've Changed," but it failed to generate much interest.
The Jackson 5 moved on to working an opening act for such R&B artists as Gladys Knight and the Pips, James Brown, and Sam and Dave. Many of these performers were signed to the legendary Motown record label, and it has been reported that Gladys Knight may have been the one to tell Motown founder Berry Gordy about the Jackson 5. Impressed by the group, Gordy signed them to his label in 1968.
Relocating to Los Angeles, Michael and his brothers started work on their music and dancing with their father as their manager. They lived with Gordy and also with Supremes singer Diana Ross when they first arrived there. In August 1969, the Jackson 5 was introduced to the music industry at a special event, and later served as the opening act for the Supremes. Their first album, Diana Ross Presents the Jackson 5, hit the charts in December of that year. It's first single, "I Want You Back," hit No. 1 on the Billboard Hot 100 chart in January 1970.
More chart-topping singles quickly followed, such as "ABC," "The Love You Save," and "I'll Be There." At the age of 13, Jackson launched a solo career in addition to his work with the Jackson 5. He made the charts in 1971 with "Got to Be There" from the album of the same name. His 1972 album, Ben, featured the eponymous ballad about a rat. The song became Jackson's first solo No. 1 single.
For several years, Michael Jackson and the Jackson 5 maintained a busy tour and recording schedule, under the supervision of Berry Gordy and his Motown staff. Gordy wrote many of the songs recorded by the group and by Michael Jackson as a solo artist. The group became so popular that they even had their own self-titled cartoon show, which ran from 1971 to 1973.
