Jón Þór "Jónsi" Birgisson is an Icelandic musician; he is the vocalist and multi-instrumentalist for the Icelandic post-rock band Sigur Rós. He is known for his use of a cello bow on guitar and his "angelic" falsetto or countertenor voice. He is blind in his right eye from birth as a result of a broken optic nerve from the brain. Apart from Sigur Rós, Jónsi also performs together with his ex-partner Alex Somers as an art collaboration called Jónsi & Alex. They released their self-titled first book in November 2006, which was an embossed hardcover limited to 1,000 copies. The two also released the album Riceboy Sleeps, in July 2009. They announced their separation in 2019, after having been together for 16 years.
