You know Jón þór Birgisson, or Jónsi, as the guitarist and vocalist for Icelandic post-rock band Sigur Rós, with trademarks such as his falsetto voice and use of cello bow on guitar, but the artist has set out on his own with debut album Go. The album, featuring nine songs drawn from material crafted during his time with Sigur Rós, is arranged in collaboration with classical composer Nico Muhly and exhibits album artwork by his sisters Inga and Lilja.
