One of the odder comparisons I've ever read.

Both groups are as close as one can get to being cult artists while still releasing Top 10 albums on a regular basis. And both attract an audience that comes primarily to gawk at the musicianship. In Rush's case, the response is a little more literal: instead of circle-dancing or staring wide-eyed at the band, fans play air drums along with Neil Peart (whose amazing dexterity and stone-faced Vulcan look make Rush the only power trio whose undisputed star is the drummer). And in an era where obvious backing tapes and flat-out lip-synching have spread well beyond the Britney circuit to rock bands like Creed and Korn, it's telling that two bands who are all about live playing, warts and all, drew some of the summer's biggest crowds.

Thanks to Tim for the tip.
