Sophie Xeon (17 September 1986 – 30 January 2021), better known mononymously as Sophie (stylised in all caps), was a Scottish musician, record producer, singer, songwriter, and DJ.

Known for a brash and "hyperkinetic" take on pop music, Sophie worked closely with artists from the PC Music label, including A.G. Cook and GFOTY, and produced for acts such as Charli XCX, Vince Staples, Kim Petras, Madonna, Nicki Minaj, and Namie Amuro.

Sophie, who initially remained anonymous and later came out as a trans woman, came to prominence with singles such as "Bipp" (2013) and "Lemonade" (2014), which were collected on the 2015 compilation Product. Sophie's debut album Oil of Every Pearl's Un-Insides followed in 2018, earning a nomination for the Grammy Award for Best Dance/Electronic Album. After Sophie's accidental death in 2021, Pitchfork called Sophie "the influential British producer who molded electronic music into bracingly original avant-garde pop".

Identity

Sophie was described as a reclusive figure, and remained anonymous for some time, concealing Sophie's identity in interviews by masking Sophie's voice or covering parts of Sophie's body. Early in Sophie's career, Sophie's real-life identity was the subject of press speculation. Prior to coming out as a trans woman, some commentators accused Sophie of "feminine appropriation", on the assumption that Sophie was a man using a female stage name. 

In a 2013 Pitchfork e-mail interview, when asked about the choice of 'Sophie' as a stage name, Sophie responded: "It tastes good and it's like moisturizer." At one Boiler Room show, drag performer Ben Woozy was recruited to mime a DJ set while Sophie pretended to be a bodyguard.

The music video for "It's Okay to Cry", released in October 2017, was the first time Sophie's voice and image were used in a release, with Sophie appearing nude from the bust up against a backdrop of clouds. This was widely interpreted as a coming out announcement as a trans woman. Sophie confirmed her trans identity in subsequent interviews, also speaking of feeling boxed-in by labels and describing music as Sophie's "chosen method of communication" and self-expression. Representatives informed Pitchfork that Sophie preferred not to use gendered or nonbinary pronouns.

Death

Sophie died at around 4 a.m. local time on 30 January 2021, aged 34, at home in Athens, Greece. Sophie's death was reportedly caused by slipping and falling after climbing up to watch the full moon.
