Tenacious D 'To Be the Best' (video)
Hilarious hard-rocking duo Jack Black and Kyle Gass are back together as Tenacious D, and according to the new video for "To Be the Best," all it took was killing Val Kilmer.

The new six-minute clip tells the story of the D's reunion and subsequent musical training from none other than Dave Grohl and Josh Groban. The result? About a minute and a half of new music, but the cameo-filled video is definitely worth a watch.

The duo's first album in six years is titled Rize of the Fenix and will be available May 15 via Columbia. Check out the brand new video for "To Be the Best" below.
