Short answers, pulled from the story.
Siouxsie and the Banshees were formed in London in 1976 by vocalist Siouxsie Sioux and bassist Steven Severin. The two had met at a Roxy Music concert in September 1975 and made their first live appearance at the 100 Club Punk Festival on the 20th of September 1976.
Siouxsie and the Banshees released eleven studio albums over their career, from The Scream in 1978 to The Rapture in 1995. They also released thirty singles during that period.
Their cover of the Beatles' "Dear Prudence," released in September 1983, was their biggest UK hit, reaching number 3 on the Singles Chart. Their album Kaleidoscope peaked at number 5 on the UK Albums Chart in 1980.
Joy Division, the Cure, U2, the Smiths, Radiohead, Massive Attack, Tricky, and Jeff Buckley are among the acts who have publicly cited the Banshees as an influence. Garbage singer Shirley Manson said she learned to sing by listening to The Scream and Kaleidoscope.
The band disbanded in April 1996 after twenty years. Siouxsie attributed the split to "the situation with Polydor" and "internal problems as well." Polydor had dropped the band from its roster shortly after the release of The Rapture in 1995.
Robert Smith of the Cure served as guitarist for the band on two separate occasions, first in 1979 after Kenny Morris and John McKay quit mid-tour, then again from November 1982 to 1984. John McGeoch played guitar from 1980 to 1982 and is widely regarded as one of the band's most influential contributors.
