Swedish experimental-pop duo, The Knife, have been around for a while but keep a VERY low profile. They avoid the press and publicity in general and rarely do interviews. I stumbled upon them while vacationing in Bangkok and have not seen or heard one peep about them in the U.S.
The Knife is Olof Dreijer and Karin Dreijer Andersson. They are based in Stockholm, Sweden and have made music together since 1999, released on their own label Rabid Records.
