But when it comes to celebrity cameos from musicians, Game of Thrones
has actually been flirting with the line between "cute" and "distracting" for a while. The drummer from Coldplay played a drummer at the Red Wedding. Sigur Rós turned up to play a glacial rendition of "The Rains of Castamere" at Joffrey and Margaery's wedding. Last year, the entirety of Of Monsters and Men popped up as musicians in a Braavosi theater troupe. And last night's premiere even snuck in another musician cameo , with Mastodon's Brann Dailor briefly appearing as a White Walker.
