Sigur Ros frontman Jón Þór Birgisson, along with partner Alex Somers have announced they will be releasing an all instrumental on July 20th. According to the artists, who will be releasing the album under the moniker Riceboy Sleeps, the 68-minute album is 'played solely on acoustic instruments in Iceland (and featuring long-time string collaborators Amiina, as well as the Kopavogsdaetur choir) and then endlessly toyed with on solar-powered laptops in a raw food commune in some far corner of Hawaii.'
