In 2004, she started a solo career.
When Sioux was 14, her father died from complications of alcoholism. At age 15, she suffered ulcerative colitis, an experience she described later as "surreal": "it completely de-romanticised the body for me."
While growing up, Sioux was often left to look after herself in an undisciplined atmosphere. Before his death, her father's alcoholism kept him incapacitated, forcing her mother to work full time. The garden at their home north of Petts Wood grew into a jungle, with high hedges and rambling roses, until the neighbours complained.
During her teens, she was a self-confessed loner, was into the music of David Bowie, Lou Reed, Roxy Music, T. Rex, The Velvet Underground and The Stooges, and she started visiting the local gay discos. She became very-well known in the London punk scene for her glam, fetish and bondage attire, which became staples of punk fashion.
In the mid-1970s, journalist Caroline Coon created the Bromley Contingent term to talk about a group of eccentric teenagers devoted to the Sex Pistols. Siouxsie was a member of the Contingent, along with fellow Banshees founder Steven Severin.
Sioux's first gig was with her group Siouxsie and the Banshees, as an unrehearsed fill-in at the 100 Club Punk Festival - two nights in September 1976 - organised by Malcolm McLaren. The group didn't know or play any songs; they improvised as Sioux recited poems and prayers she had memorized.
The same month, the Bromley Contingent followed the Sex Pistols to France, where Sioux was beaten up by someone for wearing a cupless bra, black vinyl stockings and a black armband with a swastika on it. This was used to shock the bourgeoisie, not as a political statement. To stop controversy, she later wrote the songs "Metal Postcard (Mittageisen)" (to the memory of the anti-Nazi artist John Heartfield) and the single "Israel".
One of Sioux's first public appearances was with the Sex Pistols on Bill Grundy's television show in December 1976. In the course of Grundy's interview with the members of the Sex Pistols, the presenter tried to flirt with her. In reaction, Pistols guitarist Steve Jones called him a "dirty fucker", which created a media furor that had a major impact on the Pistols' subsequent career.
In 1981, Siouxsie formed the group The Creatures with Banshees drummer Budgie, to record music more based on percussion.
In 1982, the British press greeted the Siouxsie and the Banshees album A Kiss in the Dreamhouse enthusiastically. Richard Cook in the NME finished his review with "I promise. This music will take your breath away."
In April 1996, after recording a series of 11 successful studio albums, Siouxsie and the Banshees announced their split during a press conference called "20 minutes into 20 years".
In 1995, she released the song "The Lighthouse" on the French producer Hector Zazou's album Chansons des mers froides (Songs from the Cold Seas). Sioux and Zazou adapted an excerpt of the poem "Flannan Isle" by English poet Wilfred Wilson Gibson into lyrics. The song included the incantations of a female Nanai shaman recorded in Siberia, and musical performers included Budgie and Mark Isham.
In 1998, John Cale was the organizer of the "With A Little Help From My Friends" festival that took place at the Paradiso in Amsterdam. The concert was shown on deutsch national television and featured a song of Siouxsie especially composed for the event and still unreleased, "Murdering Mouth" sung in duet with John Cale. The following year, she performed another duet with this time Marc Almond on his Open All Night album. The song was called "Threat Of Love".
In 2003, Sioux was asked to compose and sing the title track to Basement Jaxx's album Kish Kash. One year later, she toured for the first time as a solo act combining Banshees and Creatures songs : a live DVD called Dreamshow captured the last London concert of September 2004 performed with the Millennia Ensemble. Released in August 2005, this DVD reached the number one position in the UK music DVD charts. Due to that success, Universal signed her on the W14 label. Her first solo album MantaRay was released on September 2007, preceded by the "Into a Swan" single. The album gained critical acclaim. The influential site Pitchfork Media wrote "She really is pop" before finishing the review by "It's a success".
After a series of summer festivals, Siouxsie performed the last show of the "Mantaray and more tour" in London late September : this concert was filmed to be released on DVD in a near future. The singer will be performing at the "World Soundtrack Awards" in Ghent in Belgium on 18 October 2008: she will be singing on three numbers.
(In 1981), the press began to describe them as a goth band. I never thought of them as goth. Goth has never been particularly angry, just a little dismayed. It had a weak, submissive side to it. Siouxsie & The Banshees always had a real edge to what they did. There was so much articulated spite, humour, politics with a small 'p' there that I never felt they went down that simple, gloomy path. People try to pass them off as a goth band because they find them dangerous and don't understand them. Today, I can see and hear the Banshees' influence all over the place.Shirley Manson, excerpt of the Foreword of the Siouxsie & The Banshees biography by Mark Paytress (2003)
In June 2005, she won the Icon Award at the Mojo Honours in London.
In 2007, she appeared in advertising materials for a line of false lashes from cosmetics company, Shu Uemura. She recently announced on BBC Radio 2's The Weekender that she and Budgie are not musical partners anymore. In an interview with The Sunday Times in August 2007, she clarified that they had divorced. In an interview with The Independent, she said, "I've never particularly said I'm hetero or I'm a lesbian. I know there are people who are definitely one way, but not really me. I suppose if I am attracted to men then they usually have more feminine qualities.
