Brooklyn's The National have recorded a song for the Season 2 Game of Thrones soundtrack. Titled "The Rains of Castamere," the song is inspired by George R.R. Martin's beloved A Song of Ice and Fire series tells the story of Lord Tywin Lannister's brutal victory over the House Reyne of Castamere. As you might expect, the song eschews modern instrumentation in order to better fit in the medieval era of the novels.
