Sigur Rós have unveiled the full version of 'The Rains of Castamere', which is taken from the soundtrack of the fourth season of Game of Thrones.

Possible spoiler below the video!

Listen to the track below, and head here for The National's version of it from back in 2012.

They played the track in last night's episode, though we haven't watched it yet (don't tell us what happened).
