This soul scorching film follows the ups and downs of the greatest rock band in history, Tenacious D, as they embark on a large-scale world tour. The documentary follows the band on the highs of playing to devoted crowds in an unprecedentedly involved stage show in which they splay the second half of their set from the bowels of hell. It also follows the guys through the lows of their feature film Tenacious D in the Pick of Destiny falling flat at the box office, threatening the would-be triumph of these undisputed kings of rock. ~ Cammila Albertson, Rovi
