Initially influenced by Elvis Presley, Gillan started and fronted several local bands in the mid-1960s, and eventually joined Episode Six when their original singer left. He first found widespread commercial success after joining Deep Purple in 1969. He resigned from the band in June 1973, having given a lengthy notice period to their managers. After a short time away from the music business, he resumed his music career with solo bands the Ian Gillan Band and Gillan, before a year-long stint as the vocalist for Black Sabbath in 1983. The following year, Deep Purple reformed and two more successful albums followed before he left in 1989. He returned to the group in 1993, and has remained its lead singer ever since.
