Scottish folk group Trembling Bells have released 'Sweet Death Polka'. Directed by Eva Gnatiuk, the video is rather unnerving, finding the band "swallowing semi-precious stones and transmogrifying into knitted voodoo dolls of themselves, sword fighting as some of their heroes (including Melvyn Bragg, Sun Ra and Emily Dickinson) and dancing with Death." Quite the concept. Watch above.

"Sweet Death Polka" certainly lives up to its name, blooming from lyrically grim but otherwise quaint British folk to doom psych freakout over its six minutes, the track's barely restrained rural menace not unlike that channeled in Robin Hardy's "The Wicker Man." Perhaps the band have been spending too much time with Bonnie 'Prince' Billy? They start a UK tour on June 20 in Glasgow and will play across the UK until rounding out the tour in Stirling in August for Doune The Rabbit Hole. Check the dates here.
