Cocteau Twins was a Scottish dream pop band active from 1979 to 1997. They were formed in Grangemouth by Robin Guthrie (guitars, drum machine) and Will Heggie (bass), adding Elizabeth Fraser (vocals) in 1981 and replacing Heggie with multi-instrumentalist Simon Raymonde in 1983. The group earned critical praise for their ethereal, effects-laden sound and the soprano vocals of Fraser, whose lyrics often eschew any recognisable language. They pioneered the 1980s alternative rock subgenre of dream pop.
