Swedish electronic duo Koop create flowing and romantic music that is so dense and layered it sounds like a full orchestra of session players. But, in fact, they rely solely on samples, a process that often takes months to complete. Magnus Zingmark and Oscar Simonsson first began making music together in the mid-1990s after meeting in Uppsala, Sweden. After a move to Stockholm in 1997, the duo released their debut album, Sons Of Koop. In 2002, their second album, Waltz For Koop, catapulted them into the forefront of the "nu-jazz" scene. The group subsequently released Koop Islands in 2007, an album that transported its listeners back to the dinner jazz sound of the 1930s and '40s.
