Game Of Thrones star Aidan Gillen stars in the new music video from Irish post-punk band Fontaines DC.

The group – nominated for the Mercury Prize last year – announced their new album A Hero’s Death will launch on July 31.

The title track was released on Tuesday alongside a surreal music video starring Gillen, best known for playing Petyr “Littlefinger” Baelish in Game Of Thrones.

In the video, Gillen, a huge fan of the band, plays a charismatic chat-show host who finds himself disliked and overshadowed by his puppet co-host, as reality becomes blurred.

Announcing the new album, a follow-up to the critically lauded Dogrel, the band said on Twitter: “It feels like time hasn’t ticked since we announced our first record just over a year ago.

“We wrote these songs during the 12 months after finishing Dogrel as a necessary reaction to assure ourselves we will always be the band we set out to be.

“A sincere thank you to everyone who has supported our music since and before then.”

Fontaines DC – consisting of members Carlos O’Connell, Conor Curley, Conor Deegan III, Grian Chatten and Tom Coll – formed in Dublin in 2017.

They were nominated for the Mercury Prize last year but lost out to London rapper Dave, who won for Psychodrama.
