Sondre is a Los Angeles-based Norwegian singer, songwriter, film score composer and artist. His eclectic and melodic debut, Faces Down, written and recorded at 16, was listed as one of the most remarkable debuts of 2002 by Rolling Stone, also winning a Norwegian Grammy for Best Newcomer.

Anticipated follow-up Two Way Monologue was a 2004 Album Of The Year in Uncut, and he toured extensively across the world both solo, with his band, and later with the likes of Air, Stereolab Elvis Costello and St Vincent. In 2006, alone, he scored a Billboard Top 5 Jazz album, Duper Sessions, recorded the rambunctious Phantom Punch, as well as composing the score and soundtrack for the Steve Carell/Juliette Binoche hit movie Dan In Real Life, which included a duet with Regina Spektor. Lerche has also collaborated on stage with Milton Nascimento and Philip Glass. Said the LA Times about 2009's lush Heartbeat Radio: "No matter what genre he's working in (...) his refrains always pay off". Lerche co-wrote the song "Dear Laughing Doubters" for the 2010 comedy Dinner For Schmucks.

In 2011 he made his second appearance on David Letterman's Late Show, performing from his spirited self-titled (and first self-released) album, while in 2012 he had the honor of appearing on an official postage stamp in Norway. The 2014 release of his score for Sundance indie-hit movie The Sleepwalker, was followed by Please, which Popmatters called "a pop masterpiece”, naming it one of the finest albums of the year. 2017’s groovy and flamboyant Pleasure was a "thrilling sonic reboot", according to Allmusic, followed by an extensive and intense 100-date world tour, and, in 2018, the stripped down come-down, Solo Pleasure + music for the Norwegian children's television icon Fantorangen. He just wrote his first collection of essays, and released the album Patience, which Popmatters says "joins its predecessors, Please and Pleasure, to form a loose trilogy that stands as the finest work of Sondre Lerche's career."
