Like Spinal Tap, the Rutles, and even the Bonzo Dog Band, Tenacious D manage to send up rock conventions while employing them expertly. The soundtrack to their first full-length motion picture mixes songs and bits from the movie, but it plays like a hilarious concept album more than anything. Dave Grohl and (one half of the) Dust Brothers--who played on the D's delicious 2001 debut--are here joined by Meat Loaf and Ronnie James Dio. The title song navigates power balladry from the late '80s and early '90s in ways most awesome, while also throwing in a bridge that rips on faux-mystical elf-progisms of '70s stadium rock. At times the songs get a bit too meta (e.g. "He who is groovy must be in my movie"), but quibbling about self-referentiality when it comes to a fake band that calls itself "The Greatest Band on Earth" and who sings that their movie is "better than-uh Citizen Kane-uh" is perhaps to not have much of a sense of humor. --Mike McGonigal
