Midnight Oil was an Australian rock band active from the early 1970s until 2002. The band was known for its driving hard rock sound, intense live performances, and its overt left-wing political activism, particularly in aid of environmentalist causes.
The lineup included Rob Hirst on drums, Peter Garrett on vocals, Jim Moginie on keyboard/guitar, and Martin Rotsey on guitar. Andrew James was the band's first bass player followed by Peter Gifford from 1980 and he was replaced in 1987 by Bones Hillman.
