Tenacious D

Tenacious D (sometimes referred to as "The D" and often introduced as "The Greatest Band in the world. Period" is an American satirical rock duo formed by musicians and actors Kyle Gass and Jack Black in Los Angeles, California in 1994. Their music fuses vulgar absurdist comedy with rock music in a style that critics have described as "mock rock". The band first gained reputation in 1999, starring in a self-titled HBO TV series. The drumming on both of their albums and the devils voice on the track Beezleboss (also the one who plays Satan in The Pick of Destiny movie) was performed by Dave Grohl (of Nirvana, Foo Fighters and Queens of the Stone Age fame).
