The Knife

Since 1999, Swedish siblings Karin Dreijer Andersson and Olof Dreijer have made fractured dance-pop as the Knife. Notoriously mysterious, the duo is never photographed without masks on, and until recently refused to perform live. Greater stateside interest in the pair's music, which followed on the heels of critical praise throughout Europe, lead to increased exposure, as well as the domestic release of its 2006 stunner, Silent Shout.
