I can't stand Rush. They don't do very good job "reviving" the sound of classic rock. One band that does immitate classic rock very well is Wolfmother. They weren't formed too long ago. They're from Australia. The lead singer sounds a little like Robert Plant and their guitarist is pretty badass also (although no where near as good as Jimmy Page or Hendrix, but who is these days except for MAYBE ALMOST John Frisconte from the Red Hot Chili Peppers?) They only have one CD released (it's self titled) so check'em out. I promise you won't be dissapointed if you're a fan of classic rock like me.
On the note of "emo" bands, some are pretty good. Taking Back Sunday is really good. However, I do agree that Nirvana was the downfall of REAL rock music. After Jimmy Page, mothers just stopped giving birth to extrordinary guitarists except for Van Halen and a few others. I like some metal, though. Mostly more of the melodic metal stuff instead of "extreme to the point where we scream entire songs and you can't understand a word we're saying" type of metal. Avenged Sevenfold is good, though. I HATE Disturbed and Slipknot with a passion.
