What do you get when you mix a 25-year-old punk rock subculture with one of the largest non-profit scientific and educational institutions in the world? The documentary “Inside Straight Edge” of course! Narrated by Sonic Youth’s Thurston Moore, the film is running this week on the National Geographic Channel and traces the roots and culture of the no drugs, no drinking lifestyle created by Minor Threat. One problem: straight edge kids aren’t allowed to watch cable. Seriously. It’s right there in the rule book between no fucking and no caffeine. Look it up.

Minor Threat - Straight Edge

Here’s what Nat Geo says about the film:

Youth can be a minefield: drugs, sex, violence, and peer pressure. One group has an extreme way of dealing with it. They call themselves Straight Edge, and while they are being classified as a violent gang in areas such as Salt Lake City and Reno, they aren’t like any other gang you know: they reject drugs, drinking, smoking, and even casual sex. They’re rebels against a society in which everything goes. National Geographic goes inside this growing youth movement caught between being a refuge for Americas kids and a dangerous gang wanted by authorities.

And here’s a clip:
