Lætitia Sadier (born 6 May 1968, sometimes known as Seaya Sadier) is a French musician, best known as a founding member of the London-based avant-pop band Stereolab. In 1996, while Stereolab was still active, she formed the side project Monade. In 2009 – the same year Stereolab became inactive – she ended the Monade project and began to perform solo work under her own name; her current band is known as the Lætitia Sadier Source Ensemble. She has frequently performed guest vocals and collaborations with other artists. Career Stereolab Sadier was working as a nanny when she met McCarthy guitarist Tim Gane at one of the band's Paris gigs during the late 1980s. She was disillusioned with the rock scene in France, and soon moved to London to be with Gane and to pursue her career. She contributed vocals to McCarthy's final albums, and when McCarthy broke up in 1990, she and Gane immediately formed Stereolab. For the first incarnation of the band, they enlisted ex-Chills bassist Martin Kean, drummer Joe Dilworth and Gina Morris on backing vocals. In 1993, the band were signed to the American major label Elektra. They were released from their recording contract in 2004. Sadier was the main contributor of lyrics, written in both English and French. In 2009, the group went on hiatus. Monade and solo work In 1996, Sadier formed Monade with Pram's Rosie Cuckston. The group released the singles "The Sunrise Telling" and "Witch Hazel/Ode to a Keyring" in 1997. The band's debut album Socialisme ou Barbarie: The Bedroom Recordings was released on Duophonic Records in Europe and Drag City in the US in 2003. Their second album A Few Steps More was released on Too Pure in 2004. Monade's follow-up, Monstre Cosmic, was released in February 2008 on Duophonic. She retired the project in 2009 to perform new songs under her name, and released a solo album titled The Trip in September 2010; it was followed by Silencio in 2012 and Something Shines in 2014. Sadier released the album Find Me Finding You in 2017, credited to the Lætitia Sadier Source Ensemble.
