Mastodon aren’t relaxing in the run-up to their December UK tour. Last week they released the video for their latest single, Steambreather. Last night they appeared in the season finale of Game Of Thrones. And today they announce Cold Dark Place, a new EP featuring four previously unreleased songs.

Filmed in London by the husband and wife team of Essy May and Stevie Gee, the Steambreather video examines what happens when a disparate group of people accept an invitation to examine “The Breath of Life – Release Your Inner Self”.

Taken from Emperor of Sand, their eighth studio album and first to top Billboard’s Top Album Sales Chart, the track follows Show Yourself, the band’s highest charting song to date.

Increasing their mainstream exposure even more, band members Brann Dailor, Brent Hinds, and Bill Kelliher made a return to Game Of Thrones, portraying White Walkers in the latest episode, The Dragon and the Wolf. The trio, again without bass player Troy Sanders, previously appeared as Wildlings during season five of the hit series.

Back on more familiar territory the rock band from Atlanta, Georgia are readying the release of Cold Dark Place, set for release on 22 September. Three tracks (North Side Star, Blue Walsh, and Cold Dark Place) were recorded during the making of 2014’s Once More ‘Round The Sun with producer Nick Raskulinecz. The fourth track, Toe to Toes, was produced by Brendan O’Brien during the Emperor of Sand sessions.

“Emperor of Sand is like the grim reaper,” Dailor said back in March, when the album was released. “Sand represents time. If you or anyone you know has ever received a terminal diagnosis, the first thought is about time. Invariably, you ask: ‘How much time is left?’”

“We’re reflecting on mortality,” added Sanders. “To that end, the album ties into our entire discography. It’s 17 years in the making, but it’s also a direct reaction to the last two years. We tend to draw inspiration from very real things in our lives.”
