While we’re talking about watching rock music and getting choked up, I ought to mention that Anvil! The Story of Anvil is finishing its limited engagement at Sundance 608 on Thursday, September 24. It’s a movie about perseverance; more precisely, how to tell the difference between perseverance and stupid, life-ruining stubbornness, and how to stay just on the right side of the line. Also about heavy metal. But you don’t have to care about heavy metal. This might be the best movie of the year.
