"Blackwater" was the best episode from last year's season of Game of Thrones, and it ended perfectly by having The National perform "The Rains of Castomere" over the closing credits (click here to download the song).  HBO has released a new teaser trailer for Season 3, and they've used the song as the creepy three-eyed raven flies over the modern-day world as our return to Westeros approaches.

Hit the jump to check out the teaser trailer.  Game of Thrones returns March 31st.

Via HBO.
