Tonight’s Game Of Thrones is a must-watch, not only because of some huge events that take place but also because Sigur Rós will be scoring some of said events. Their version of traditional Westeros folk song “The Rains Of Castamere” (which was previously covered by the National) will appear in tonight’s episode. Their ethereal take on things isn’t as entertaining as HBO”s mixtape of rappers going on about the series but it’s certainly good at instilling a deep sense of foreboding.

“The Rains Of Castamere” is available on Amazon.
