Sandoval formed The Warm Inventions in 2000 and released her first solo album "Bavarian Fruit Bread" in 2001, which she recorded with My Bloody Valentine drummer Colm Ó Cíosóig. The album differed in terms of theme, voice, and instrumentation from that of her work with Mazzy Star. Bert Jansch plays guitar on two tracks, and the album features two covers, "Butterfly Mornings" from the film "The Ballad of Cable Hogue" (1970) and Jesus and Mary Chain's "Drop". The Warm Inventions released two EPs, "At the Doorway Again" in 2000 and "Suzanne" in 2002 but did not win commercial success, with one video on MTV and little radio play. Sandoval recorded a song, "Wild Roses", for a compilation CD released by Air France, "In the Air" (2008).
