Composer/producer/multi-instrumentalist Jóhann Jóhannsson is one of Iceland's most prolifically creative musicians, as a solo artist as well as a part of the Kitchen Motors label and collective (which also includes members of Sigur Rós, Múm, and Slowblow) and also Apparat Organ Quartet. Kitchen Motors' aesthetic, which focuses on largely improvised and electronic music, also applies to his other projects. Apparat Organ Quartet, with music described as "machine rock & roll," consist of four keyboardists who play discarded vintage instruments that they refurbish and a drummer. Jóhannsson's work on his own ranges from delicate laptop pop to sound art installations in galleries to collaborations with Barry Adamson, the Hafler Trio, and Pan Sonic. His first solo album, 2002's Englabörn, paired a string quartet with percussion, keyboards, and electronics in a series of bittersweet miniatures, while 2004's Virthulegu Forsetar was a much more expansive work scored for brass, organ, keyboards, and electronics that was composed for and recorded in Reykjavik's Hallgrimskirkja Church. The British label Touch released both of these albums, but 2005's Dis was issued by Worker's Institute.
