There is more than one artist with this name: 1) Jón Þór Birgisson, aka Jónsi, is the guitarist and vocalist for the Icelandic band Sigur Rós. He is universally known for his soft inimitable falsetto voice. He has also released an album as one half of Jónsi & Alex with his boyfriend Alex Somers, formerly of the band Parachutes. Jónsi's solo album, Go, was released on April 6th 2010. In his solo venture Jónsi departs from the ethereal, dreamy landscapes present in Sigur Rós' music and instead concentrates on shorter, more instant 'portrait' tunes.
