Sigur Ros frontman released his debut album Go in 2010. Jonsi initially though he would be making a low-key, acoustic album until, as he says, "somewhere along the line, it just sort of exploded." That explosion resulted in sheer aural fireworks. Not a straight ahead pop record, nor rock, folk, ambient or electronic, it encompasses all of these to create an expansive musical palette that's been brought to life by Jonsi alongside a number of free-spirited collaborators including Philip Glass the percussive genius of Samuli Kosminen.
