Stereolab
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 moved to London in 1989 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 into recording hiatus although they continue sporadically to play together live.

In 2007, Sadier wrote songs with Mouse on Mars and toured with them in Italy. They have yet to record the songs for release. In 2009 the French label Deux Mille released an EP which features Sadier singing with Toulouse-based band Momotte. Sadier wrote and sang the lyrics to the track "Quick Canal" by Atlas Sound on their album Logos (2009). She contributed vocals to "PartyIsntOver/Campfire/Bimmer" on the album Wolf (2013) by Tyler, the Creator, and "Summer Long" on the album Alexandre (2014) by Brazilian band Mombojó.

In 2020, Sadier appeared as featured lead singer on two compositions by Chapman Stick virtuoso Michael Bernier, released on his third solo full-length release The Beach Album. Together with Jarvis Cocker she released in 2021 on the album Tip-Top Chansons d´Ennui a cover version of French classic Paroles, Paroles originally sung by Dalida and Alain Delon.

On 13 November 2023, Sadier announced her fifth solo album, Rooting for Love, with a release date of 23 February 2024 by Drag City. On it she is joined by a vocal ensemble of men and women. The album's central theme, Sadler says, is "a call for Gnossis" which she describes as "an inquisitive outlook that will lend clue to the traumatised civilisations of earth." It follows a nature-based theme.

Issued recordings
Primary material
Issued recordings
These are published sound issues catalogued under the name. Most postdate the works they carry, and an issue is never counted here as a work of composition. 4 issues carry dates between 2010 and 2024. The run opens with The Trip and closes with Rooting for Love. The 2010s are the densest part of the run, with 3 titles, and that concentration is a fact about what the registers have catalogued rather than a judgement on the work itself.
Recordings and discography
Primary material
Recordings and discography
The discography assembled here shows how Sadier's work has been published in sound, not what Sadier made. 15 sound issues are catalogued, carrying dates from 2010 to 2024. An issue is a published recording, distinct from the composition it carries, from a printed score of that composition and from any single performance of it; none of the entries below is counted in the catalogue of compositions above, and several of them carry the same work in different readings. The 2010s are the densest decade of publication, with 8 issues. The performers and issuing labels are as the discographic register states them; where it names no performer the article names none.
