High Quality Content by WIKIPEDIA articles! Sigur Rós is 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. Their name is Icelandic wordplay: while the individual words Sigur and Rós mean, respectively, Victory and Rose, "Victory Rose" wouldn't be grammatically correct; the name is actually borrowed from Jónsi's younger sister Sigurrós, who was born the same day as the band was formed, and then split into two words.
