If you decide to call your film Deathgasm then you had better make sure the result is one extremely crazy affair. And the word from the horror film festival circuit is that this movie from New Zealand (which arrives in cinemas and VOD on Oct. 2) is exactly that.

Written and directed by first-time filmmaker Jason Lei Howden, the movie concerns a pair of metalheads named Brodie (Milo Cawthorne) and Zakk (James Blake) who unwittingly summon malevolent forces. How malevolent? You can check out the new, mayhem-filled trailer for Deathgasm below to find out.
