Stereolab earned critical acclaim for albums such as 1993's Transient Random Noise Bursts with Announcements, 1995's Mars Audiac Quintet, and 1996's Emperor Tomato Ketchup; around that time, Sadier began working on her own project, Monade, recording with Pram's Rosie Cuckston. In 1998, she gave birth to her and Gane's son Alex, and the following year she returned with Stereolab for the group's Cobra and Phases Group Play Voltage in the Milky Night and 2001's Sound-Dust.
Monade's first album, Socialisme ou Barbarie: The Bedroom Recordings, appeared in 2003. Despite Stereolab member Mary Hansen's death in 2002, the band continued, releasing Margerine Eclipse in 2004; the next year, Sadier was busy with the full-band Monade album A Few Steps More and Fab Four Suture, a compilation of limited-edition Stereolab EPs. Likewise, 2008 saw the release of the third Monade album, Monstre Cosmic, and Stereolab's most accessible album in some time, Chemical Chords. Sadier's immediately recognizable voice also appeared on many other collaborations over the years, including songs with Blur, Luna, the High Llamas, and Mouse on Mars.
Stereolab went on hiatus in 2009 and Sadier began work on her first solo album, working with the Spinanes' Rebecca Gates, April March, Richard Swift, and former Monade players Julien Gasc and Emmanuel Mario. The Trip was released in 2010, the same year that another Stereolab collection, Not Music, arrived. Two years later, the more introspective, political Silencio appeared. For 2014's Something Shines, Sadier recorded in London and throughout Europe, crafting a lavish sound that recalled Stereolab's most orchestral moments. ~ Heather Phares, Rovi
