Sigur Rós ( ['sɪːɣʏr rouːs]) are an Icelandic post-rock band with melodic, classical and minimalist elements. The band is known for its ethereal sound and lead singer Jónsi Birgisson's falsetto voice.
Jón Þór (Jónsi) Birgisson (guitar and vocals), Georg Hólm (bass) and Ágúst Ævar Gunnarsson (drums) formed the group in Reykjavík in August 1994.[1] Their name is taken from Jónsi's younger sister Sigurrós (which when translated into English means 'Victory Rose'), who was born the same day as the band was formed
