WATCH: The National's Matt Berninger performs Game Of Thrones song with backing orchestra

The band previously recorded a version of ‘Castamere’ for the show back in 2012, which was later covered by Sigur Ros.

Now the score to the hit medieval fantasy show - which is filmed in Northern Ireland - is currently touring with a full choir and orchestra, with Berninger appearing as a guest vocalist in Las Vegas.

The National are planning the release of their new album - the long-awaited follow up to 2013's Trouble Will Find Me - later this year.

Meanwhile, Game Of Thrones Season 7 will return to the small screen in July.
