The Naked Lunch takes a long, heavy look at the world of heavy metal through the films of Sam Dunn, Canadian filmmaker and anthropologist (and metalhead). We take a look at both his original doc, Metal: A Headbanger’s Journey, as well as its followup, newly available on DVD, Global Metal. To help us delve into this sinister realm, we’ve enlisted the help of resident metal freak and Montreal Gazette columnist Al Kratina. Plus, we’ve added a news segment! It’s…informative.
