Wow! I hope these unreleased recordings will be available for everyone, on CD or MP3.
I am really interested by these 2:
Jónsi, Alex Somers & Paul Corley Liminal Remixes contains new, ambient versions of Sigur Rós songs, including ‘Untitled 6’, ‘Varúð’ and ‘Brennisteinn’
Alex Somers’ Alex Somers LP is a new album of music from the longtime Sigur Rós producer.
