Rarely has calculated stupidity made as much sense as in this vulgar, cartoonish rock opera, starring Jack Black and Kyle Gass as a pair of metal-worshipping musical losers in quest of stardom, redemption, and the rent money.
The occasional parties packed with opera singers happen in the kitchen, which has rift-sawn oak and metal cabinets, and a butler's pantry, which has its own refrigerator and is stocked with frozen glasses for the cocktails Ms. Clayton mixes up (her latest concoction is called "Flaming Lips" because it includes habanero peppers).
