He started out as the lead singer of the Jackson Five, a band made up of his brothers and sisters. He was the youngest in the group but he got to be the lead singer.
By the time he was 10, the band had a record deal. Their first four singles all went to number one in the US charts - they were massive. The Jacksons made 20 albums - the last was in 1984.
Michael stayed in the band but also had a solo career. His first solo hit was in 1972.
