Green Room (2015)
Green Room is the slasher that you didn't even know you needed. If you haven't been in a touring band, or ever been interested in punk music at all, this is a great introduction to the destabilized lifestyle that people have to adapt to follow their sonic dreams in a lot of cases. However, it's highly unlikely that you'll end up having to defend yourself and your bandmates from deranged nazis at any point in your careers. Rock on.
