The Knife are a Swedish electronic music duo from Stockholm, formed in 1999. The group consists of siblings Karin Dreijer Andersson and Olof Dreijer, who together also run their own record company, Rabid Records. The group gained a large international following in response to their 2003 album Deep Cuts. The group and this specific album later received further attention when a cover of their song "Heartbeats", rearranged for acoustic guitar by Jos Gonzlez, appeared in a Sony commercial. Subsequent songs have appeared on a number of television shows.
The duo's first tour took place in 2006, along with 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.
