One of the films that will no doubt leave an impression at this year’s SXSW Film Festival is Jason Lei Howden’s Deathgasm, a heavy metal shocker fueled by demons, punk rockers and plenty of carnage. On the heels of the announcement that Deathgasm would be joining the Midnighters lineup at SXSW next month is the film’s first teaser trailer, and boy is it a good one.

As the next big festival is just around the corner, indie gems just like this one will be popping up all over the place with Deathgasm kicking things off in brilliant fashion. The trailer is about as NSFW as one can get, so prepare yourselves, sit back and watch the insanity ensue.

New kid in town Brodie and bad-boy Zakk quickly bond over their mutual admiration of heavy metal. But when these two metal thrashing losers unwittingly summon malevolent forces, their dreams of stardom may just have to be put on hold.

Deathgasm stars Milo Cawthorne, James Blake, Kimberley Crossman, and Stephen Ure. It has its World Premiere next month at SXSW.
