Definitely one of the best bands ever. I had the extreme good fortune to see them live back in '95 and I can honestly say that out of the 100+ concerts I've been to it was by far the best.

The very fact that young people are talking about this 33 years after Dark Side of the Moon was released says a lot. I seriously doubt that 30 years from now you'll see a poll asking " Is (insert name of modern band)the best band ever?"

Zep is great too, and of course the Beatles, plus The Who, Rolling Stones, etc. So much great music came out of the late 60's/early 70's. You just don't see that kind of talent coming together anymore.
