Aerosmith.....they still got it
You know who really still has it? RUSH. They are still freaking perfect in spite of how complex and difficult much of their music is. If anything, they are even better now than they were 30 years ago. There are still some shows left on the tour. Do yourself a favor and catch one if you can. If not, buy the "Snakes and Arrows" live DVD and see what is probably the best live video ever recorded. Excellent show, perfect musicianship, and three guys just having a ball playing.
