Sigur Rós are an acclaimed post-rock band hailing from Reykjavik, Iceland, formed in 1994 by Jón Þór "Jónsi" Birgisson, Georg Hólm, and Ágúst Ævar Gunnarsson. Renowned for their ethereal soundscapes, haunting falsetto vocals, and innovative use of bowed guitar, the band has become synonymous with the atmospheric and cinematic qualities of Icelandic music. Their breakthrough came with the album "Ágætis byrjun" in 1999, garnering international attention for its lush instrumentation and emotive style.

Over the years, Sigur Rós have continued to evolve, incorporating elements of classical, minimalism, and electronic music, while consistently pushing the boundaries of genre and language—often singing in both Icelandic and the invented “Hopelandic.” Their music, featured in numerous films and television shows, evokes the stark, mystical beauty of their homeland and has earned the band a devoted worldwide following. Sigur Rós have remained a seminal force in contemporary music, influencing a generation of artists with their innovative artistry and emotional intensity.
