Post-rock band Sigur Rós are set to make an appearance in the fourth season of Game of Thrones.

According to Stereogum, the Icelandic group will have an undisclosed guest spot on the HBO series, and will most likely have some music featured in the end credits. Sigur Rós isn’t new to TV appearances, as they have already showed up on and provided music for The Simpsons.

Game of Thrones has had crossovers with popular music before, such as when The Hold Steady’s track “The Bear & The Maiden Fair” was played on an episode and when CHVRCHES covered the theme song.
