Comedy starring Jack Black (School of Rock, King Kong) in his other capacity as one half of hard-rockin spoof band, Tenacious D. This is the story of how the band Tenacious D came into being; Jack Black, a green Midwestern newcomer to California, comes across Kyle Gass playing guitar on the beach and is stricken. KG is a guitar god and JB wants to be part of his life. The marriage of his classic Rock voice and KG's shredding, face-melting solos proves fruitful. Their partnership soon gives rise to the idea that the two could go for Rockin' world domination and this they set out to achieve. The road to Rock Valhalla is a long and arduous one though. To shorten it, they set out on the quest for The Pick Of Destiny - housed in a museum some miles away but promising its possessor mythological Rock immortality. However its theft proves to be a complicated business at the end of a long and winding road.
