Game Of Thrones' next season will have Sigur Rós, as well as Mark Gatiss and Michiel Huisman in familiar roles

Following third-season cameos in which the frontman of Snow Patrol and the drummer from Coldplay appeared on Game Of Thrones then were immediately killed, ending those bands’ careers forever, Entertainment Weekly has announced that Sigur Rós will appear on, then likely die in, the show’s fourth season. The band is reportedly a favorite of showrunners David Benioff and Dan Weiss, as EW notes that the duo “would often listen to their music while shooting in Iceland,” as Sigur Rós is broadcast on a constant loop from speakers embedded in the nation’s mountains. Like their songs, their death cries will no doubt be hauntingly beautiful, though you won’t understand a word.

While the exact nature of the band’s role remains a secret, Winter Is Coming claims to have uncovered the mystery of another recent Game Of Thrones casting—that of Sherlock’s Mark Gatiss. According to the actor’s own résumé, Gatiss will play the role of Tycho Nestoris, a representative of the Iron Bank of Braavos, the financial institution with a terrifying reputation for always collecting its debts, like a slightly less fearsome Wells Fargo. Fans will note that Nestoris is being introduced a bit ahead of schedule than he appears in the books, presumably as part of HBO’s strategy to start burning through them faster and faster and force George R.R. Martin to finish some new ones already.

And finally, The Hollywood Reporter recently cleared up the casting of Michiel Huisman, better known as that guitar-wrangling bad boy whom you should know better than to get involved with on Treme and Nashville. According to its report, Huisman will actually be taking over the role of Daario Naharis from Ed Skrein, replacing Skrein as Daenerys' love interest for as-yet-unknown reasons. Though most likely he just pulled out a guitar and acted all sweet yet tormented and the show just fell for him, like so many before it.
