RUSH does indeed still rock. In fact, they are one of the better-rockin' of the "older" bands. Not to be missed by any means.

Lot's of the "older" bands still rock surprisingly well. STYX comes to mind. The DEAD (reincarnation of the Grateful Dead) are damned good and the scene is the same except a skoche smaller.
RATDOG (Bobby Weir's band) rocks hard. BLUE OYSTER CULT still rocks hard, but you find them playing casinos nowadays and not so much at the festivals etc. NEIL YOUNG still plays a great show especially if he's with CRAZY HORSE. I saw ZZ TOP 3-4 years ago and they rocked hard. FOREIGNER was damn good a couple years ago. STONES still rock hard obviously and I think the same could be said of AEROSMITH.

Big thing I'm waiting for is a PHISH reunion. It will be huge. Could happen anytime. Expect a SUPERTRAMP reunion soon also!
