Sigur Rós is an Icelandic post-rock band from Reykjavík, active since 1994. The band comprises singer and guitarist Jón Þór "Jónsi" Birgisson, bassist Georg Holm, and keyboardist Kjartan Sveinsson. Known for their ethereal sound, frontman Jónsi's falsetto vocals, and their use of bowed guitar, Sigur Rós incorporate classical and minimal aesthetic elements. Since breaking internationally in 1999 with their uniquely brilliant second album Ágætis byrjun, which won the inaugural US Shortlist Prize for Artistic Achievement in Music, Sigur Rós have been a global sensation, from their six number one albums in Iceland to platinum-selling albums and sell-our tours in all directions. The band creatively fuses the apparent opposing forces of majesty and intimacy, drawing on ambient and neo-classical strains as much as rock and shoegaze, spearheaded by Jónsi’s haunting falsetto and reverberating guitar. Their music has been used in film and television hits (Planet Earth, The Simpsons, and Game of Thrones), and they have collaborated on pieces ranging from choral operas (Odin’s Raven Magic) to dance (Split Sides, composed with Radiohead).
