Gruff Rhys, a well-known Welsh musician, is preparing to release a set of disturbing "holiday" songs that lack the cheer one would expect this time of year. The EP, entitled, "Atheist Xmas," deals with some pretty intense subject matter and will be released just six days before Christmas.

According to the BBC, the EP is being described as, "an unholy trinity of three turkey-free new tracks for the festive season." The songs, of course, are morbid at best. In "Post Apocalypse Christmas," Gruff looks at the holiday "through the semi-melted eyes of a nuclear holocaust survivor."

Another tune, "Slashed Wrists This Christmas," delves into manic depression and suicide. Below, listen to the song (caution: disturbing content):

On his web site, the musician, who is also the lead singer of a band called Super Furry Animals, is promoting the three-song EP as a "secular Christmas" album. Stereogum writes, "The depressed atheists of the world now have a Christmas carol to call their own." They're probably right.

Quite an odd way to celebrate the holiday, though this is likely a PR opportunity that will work in the musician's favor.
