Amid all its myriad casting, Game of Thrones most always makes room for the odd musician (or band) to cameo somewhere in Westeros. In Season 3, we saw Coldplay’s Will Champion drumming for the Red Wedding, while this past season Mastodon participated in the battle ofHardhome,” and Season 6 will find now space for Of Monsters and Men.

Ever watchful, Watchers on the Wall uncovered photos of lead singer-guitarist Nanna Bryndís Hilmarsdóttir, singer-guitarist Ragnar “Raggi” Þórhallsson, and drummer Arnar Rósenkranz Hilmarsson relaxing between takes on the Girona, Spain set. Unlike Sigur Rós (who also previously appeared), it remains unclear if the Icelandic Of Monsters and Men will contribute any actual music to the soundtrack.

On a side note, Of Monsters and Men also recently provided music for the first Marvel’s Jessica Jones teaser, with their song “Thousand Eyes.”

Elsewhere of Game of Thrones Season 6, screen legend Max von Sydow has been cast as the mysterious Three-Eyed Raven to a returning Bran, while Deadwood alum Ian McShane will also appear in a limited, mysterious role, joining Richard E. Grant and The Babadook star Essie Davis as theatre troup players, four notable actors as the Tarly family, and Borgen star Pilou Asbæk as fan-favorite Euron Greyjoy. Apart from a list of directors, debate continually rages as to whether Kit Harington’s Jon Snow will return, even as story logistics seemingly confirm scenes set at The Wall next year.

HBO won’t start official Game of Thrones Season 6 teases until much later, but what should we hope for from Of Monsters and Men?
