Icelandic experimental rock outfit Sigur Ros took home the inaugural Virgin Megastore Shortlist Prize for Artistic Achievement in Music and its accompanying $10,000 cash prize last night (Nov. 19) at the Knitting Factory in Los Angeles. The group was one of four nominated finalists who also performed at the awards ceremony.

Soul vocalist Nikka Costa opened the show with an energetic set, followed by an acoustic performance from modern rock act the Dandy Warhols. Rapper Talib Kweli was joined for two songs during his short set by his Black Star partner Mos Def. Surprise performances by non-nominated artists David Poe and Julia Fordham helped make up for the absence of R&B act Bilal, who was on hand but did not play his scheduled set.

The winner was chosen by a panel of industry experts that included Beck, Macy Gray, and Aimee Mann just minutes before the show started. Designed as a U.S. version of the U.K.'s prestigious Mercury Music Prize, the Short List aims to honor contemporary music's most creative and adventurous releases. The list of finalists, which also included Ryan Adams, Jay Dee, PJ Harvey, Gorillaz, and Air, was pared down from a group of 49 possible album releases.

Virgin Megastore will also make a $10,000 contribution in Sigur Ros' name in honor of the victims of the Sept. 11 terrorist attacks on New York and Washington, D.C.
