Sigur Rós and Game of Thrones are teaming up, new reports say.

The Icelandic indie band Sigur Rós will appear on the next series of "Game of Thrones".

The band is already on the "Game of Thrones" set in Croatia, although it hasn't been revealed how the boys will fit into the hit series.

Sigur Rós, made up of members Jón Þór "Jónsi" Birgisson, Georg Hólm and Orri Páll Dýrason, are the latest in a line of Game of Thrones-musician collaborations.

Previous collabs include appearances from Snow Patrol's Gary Lightbody and Coldplay drummer Will Champion. You can watch both videos below (scroll down!) They're both brief cameos....but who knows what Sigur Rós will bring?

The HBO series has fans excited for the new season, but die-hard indie buffs may be disappointed...or excited.

What do you think of the Sigur Ros-Game of Thrones mashup? Horrible, or wonderful? Sound off below!
