Sigur Rós Debut New Song off Upcoming Album

Sigur Rós had their first television performance in over ten years last night on Late Night with Jimmy Fallon, and they used the opportunity to debut 'Kveikur.'

The song is more aggressive than the band's signature ethereal sound, but it is sure to build excitement for Kveikur, due out on June 18.

Sigur Rós is also scheduled to play a show in Dublin at the O2 Arena on November 16.

Check out the performance below.
