The Knife are an electro pop duo from Sweden, formed in 1999. The group consist of siblings Karin Dreijer Andersson and Olof Dreijer, who together also run their own record company, Rabid Records. They first received international attention after their song "Heartbeats", covered by José González, appeared in a commercial by Sony. Subsequent songs have appeared on a number of television shows. Their first tour took place in 2006, as well as the release of their critically acclaimed album Silent Shout. They have won a number of Swedish Grammis, but refuse to attend awards ceremonies. They have appeared in public wearing Venetian masks. Andersson released a solo album under the name Fever Ray in 2009, while her brother released several EPs as Oni Ayhun in late 2009 and early 2010.
