Pretty much the platonic ideal of a great rockumentary: filmmaker documents band at a career-defining moment, right as they're recording their masterpiece, and then captures way more of a story than he bargained for. I could watch two more hours of Jeff Tweedy and Jay Bennett bickering about the transition between "Ashes of American Flags" and "Heavy Metal Drummer."

Young Spencer's cameo is a highlight. Also, the live stuff is great. I don't understand why they've never released a soundtrack.
