Sigur Ros: iTunes Festival Live(2013)

Distinguished by the astonishing, crystalline voice of frontman Jónsi Birgisson, the Icelandic post-rockers play from their new album 'Kveikur' at the iTunes Festival. It's their second full-length release in two years, and showcases a heavier, crunchier take on the band's epic, neo-classical soundscapes.
