Amiina: Formerly Sigur Ros' percussion section, Amiina broke rank and released their debut album, Kurr, in 2007. A peerless record for its time, the album featured instrumental tracks performed on instruments such as the theramin, the glass harp and the 'musical saw'. So not the conventional band set up. After expanding their line-up for second album Puzzle in 2010, the collective have since established a small, but loyal and perfectly formed fanbase. Beautiful music for the small hours.
