Simon,
Dont get me wrong, there have been some new bands that I have found in the last 20 years that have been great. Just not so many in the last 5 years, seems to be getting harder to find new bands that actualy have anything new to offer.
But you are completely right about finding gems from the past in older bands that we might have missed the first time round, I get far more satisfaction from finding an old lost treasure than wading knee deep through tween crap trying to find a nugget of originality.
Martin.

P.S. Everyone needs an inner-Shatner wink.
