Rising from their status of underground legends, Jack Black and Kyle Gass – the members of the self-proclaimed greatest band on Earth, Tenacious D – have procured a spot alongside heroes Led Zeppelin and Dio with the DVD collection “Tenacious D: The Complete Masterworks.”

Tenacious D, at its core, is one part spoof-metal, one part folk rock and one part Spinal Tap sans exploding drummers. With liberal doses of humor riding alongside beautiful harmonies and Gass’s excellent fretwork, it’s easy to forget that the pair are competent musicians.

“Complete Masterworks” is a comprehensive collection of the group’s television appearances, videos and HBO mini-shows. It even contains the group’s now-legendary audition at London’s Brixton Academy.

Within the 2-disc collection, there’s more than enough D to satisfy even the biggest “Psycho” fan. The HBO clips offer an interesting look into the evolution of the group from hokey side-project to legendary rock outfit. Clips show Black’s comedic capabilities in a way none of his movies truly can. Included in the episodes are the stories of how Kyle once quit the D, the group’s encounter with Sasquatch and an unsuccessful search for Inspirato.

The Brixton performance is an early D show featuring many of the tunes that became fan favorites. While the show is a little low-tech, songs like “Wonderboy,” “Kielbasa,” “Fuck Her Gently” and “Tribute” are all there in their infancy. The performance is Tenacious D’s equivalent to “The Song Remains the Same” or “Live in Central Park.” “Masterworks” is the best, if not the only, videotaped example of the pair’s stage presence and chemistry.

With the performance is a look into the group’s sense of humor, as Jack slays a dragon during “Dio” or Gass gives the ladies a peek at his caboose during “Kyle Quit the Band.”

The HBO shorts and the concert footage are the true gems in “Masterworks.” Let it never be said Tenacious D doesn’t give its fans their moneys worth. Disc two also contains all of the group’s videos and making-of specials.

Masterworks is the next best thing to actually seeing the D live. For a mere $15, the “D-VD” is the perfect introduction for neophytes or a tasty collection for longtime backstage Bettys.
