TENACIOUS D, literally rock and roll’s most important duo ever, has released the triumphant music video for 'To Be The Best'.

The six-minute epic begins with a Maria Menounos-narrated news story chronicling the band’s downfall after the pitiful performance of their film Tenacious D in The Pick of Destiny.

However, following Val Kilmer’s assassination, the duo begin the long road back to glory, enlisting the help of Dave Grohl and Josh Groban along the way.
