Valgeir Sigurðsson (born 1971) is an Icelandic record producer, mixer, composer, engineer and musician.   Valgeir's fascination with recording technology lead to a job in a small recording studio at the age of 16. He studied classical guitar and graduated with a Tonmeister degree from London's SAE Institute. As producer and collaborator he has worked in many genres of music while his own style often shifts between, or combines, post-classical and electronic music.   In 1998 Valgeir was hired by fellow countrywoman ***** as engineer and programmer on the soundtrack for Lars Von Trier's Dancer in the Dark. A song from the film, I've Seen It All (a duet with Radiohead's Thom Yorke) was nominated for the Academy Award for Best Original Song but lost to Bob Dylan's Things Have Changed. Sigurðsson created the distinctive train-rhythm that runs through the song. His working relationship with ***** continued beyond the film project and was consistent from early 1998 until 2006, during which time Valgeir was one of her main studio collaborators.   Since gaining international recognition, Valgeir has collaborated with a number of noted and diverse artists such as Kronos Quartet, múm, Bonnie 'Prince' Billy, CocoRosie, Howie B and composers Nico Muhly and Ben Frost.   Valgeir set up Greenhouse Studios in 1997, now widely regarded as Iceland's premium recording facility. In 2006 he formed the Bedroom Community record label/collective and has gone on to launch the recording career of Nico Muhly and release acclaimed albums by Ben Frost and Sam Amidon.   He has composed music for TV, film and theater and his debut solo album Ekvílibríum was released by Bedroom Community in September 2007. Following the release he has toured and performed in Europe and in the US.
