He may be one third of the Icelandic band Sigur Rós, but singer and guitarist Jón Thór Birgisson is also one part of another kind of group: the art duo Riceboy Sleeps. Together with the artist Alex Somers, Birgisson is exhibiting works on paper, soundscapes and video installations inspired by his northern homeland at London's Agency Gallery from April 11. Among the works is a dreamlike video collage, the soundtrack to which will be released as an album later this year.

According to Somers, the duo work separately, but their ideas dovetail. "We are independently creative: I draw and Jon will paint, and then we will swap," he says. "Or we will each have a camera and then put the video images together. It works because have such a similar sense of what is beautiful."
