HIT PARADE'S NOT ROCK-SOLID
6 / 10
'Rock of Ages' is what it is: a jukebox musical stringing together songs so familiar, the program lists them in small print between the hosiery credits and the union logos. If you can't identify the first seconds of 'Sister Christian,' you shouldn't be at the Brooks Atkinson Theatre to begin with. It's not as if the material's been Broadway-ified, either. Backed by an onstage band, the cast rocks out over arrangements that remain pretty close to the originals. And guess what? Familiarity does breed content. Especially if you're the kind of person who gets misty hearing 'Every Rose Has Its Thorn.'
