Icelandic rockers Sigur Ros are set to make an appearance on the upcoming season of Game Of Thrones, according to U.S. reports.

The band is currently in Croatia shooting scenes for the fantasy drama, but details surrounding their appearance and roles remain unknown.

This isn't the first U.S. Tv show appearance for the group. In May (13), they appeared on The Simpsons.

Earlier this year (13), Coldplay star Will Champion appeared on Game of Thrones' third season as a drummer, and cancer-stricken rocker Wilko Johnson portrayed a silent executioner.
