Florence + the Machine Was Who You Heard Following Last Night's 'Game of Thrones' Episode

Give the new track another listen!

Sunday night's episode of Game of Thrones featured new music from one of the world's most acclaimed acts. Warning: spoilers ahead!

When the credits rolled, "Jenny of Oldstones" was performed by Florence + the Machine, a haunting ending to an episode featuring numerous characters reuniting at Winterfell as the undead march south to face them. 

But Florence Welch isn't the only singer who lent her voice to the contemplative song. In the episode itself, Podrick Payne (Daniel Portman), a character who has risen from a meager squire through the seasons, offered an a cappella rendition of the track as friends and enemies enjoyed a drink together in Winterfell's great hall.

Welch is the only artist whose work will be featured in the final season. She agreed to perform the song after she was personally approached by the show's creators, David Benioff and D.B. Weiss.

"When I first heard the song it sounded like a Celtic lullaby to me," she said in a statement. "Celtic music has always been in my blood, so I felt like I could do something with it. The magic and ritual in Game of Thrones, not to mention the costumes, have always appealed to me. I am honored to be a part of the final season."

"We've always been huge fans of Florence's music, and the season two trailer with her song, 'Seven Devils,' was possibly the most powerful we've ever had," Benioff and Weiss shared in a press release following the episode. "So the opportunity to hear her otherworldly voice on our show was always at the forefront of our minds. We're still pleasantly shocked that she agreed to sing 'Jenny of Oldstones,' and we're in love with the result."

Also prominently featured in episode two of the show's final season is the long-gestating revelation to Daenerys Targaryen (Emilia Clarke) that her beau, Jon Snow (Kit Harington), is really her nephew, Aegon Targaryen. This means that he has a claim to the Iron Throne, upending not just their romance but also her designs on ruling Westeros. However, before they could address this glaring issue, the White Walkers were spotted bearing down on the castle, creating quite the cliffhanger.
