Jack Black and Kyle Gass perform live at London's Brixton Academy as mock rockers Tenacious D in this definitive collection, which also features an array of the duo's music videos, HBO shorts, studio footage and more. Highlights include the band's provocative 2002 Brixton concert, HBO's hilarious series chronicling the duo's early years, and the Spike Jonze-directed "Wonderboy" video with a "making of" featurette.
