[2] Sandoval has toured and collaborated with other artists, including Massive Attack, for whom she sang "Paradise Circus" on the 2010 album Heligoland[3] and the 2016 single "The Spoils".

After Smith's abrupt departure during a tour of the UK (hurling her guitar to the floor at the Hammersmith gig), Sandoval took over lead vocals.

Sandoval formed The Warm Inventions in 2000 and released her first solo album Bavarian Fruit Bread in 2001,[9] which she recorded with My Bloody Valentine drummer Colm Ó Cíosóig.

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".

[10] 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 and her band were chosen by Matt Groening to perform at the edition of the All Tomorrow's Parties festival he curated in May 2010 in Minehead, England.

[14][15][16] On March 9, 2016, it was confirmed that Hope Sandoval & The Warm Inventions would release a 7" vinyl single titled "Isn't It True" for Record Store Day 2016.

[17] The track also features Jim Putnam of Radar Bros.[18] A music video for the song was released on April 19, and is dedicated to Richie Lee of Acetone.

[19] The Warm Inventions' third studio album, Until the Hunter, was released on November 4 through the band's own independent record label, Tendril Tales.

[28] Sandoval, along with artists such as Sting, Elton John, Dolly Parton, Eric Clapton and more, was featured on the 2024 reimagined duet version of Ghost on the Canvas, the 2011 farewell album of Glen Campbell who died in 2017.

[29][30] During live performances, Sandoval prefers to sing in near-darkness with only a dim backlight, playing the tambourine, harmonica, glockenspiel or shaker.
