Back Alley Film Series screens Deathgasm. We'd be lying if we said the plotline didn't immediately make us think of cult classic Evil Dead. But despite the similarities this 2015 New Zealand film, which premiered earlier this year at South By Southwest, has a life of its own. It follows two teenage boys - both heavy metal fans - that regretfully summon an evil spirit after playing with black magic. If you like gore and demon flicks, this Back Alley Film Series pick is right up your alley.
