I know I've been away too long when people are bumping up threads from 7 years ago...it only seemed like a couple of weeks, but maybe it was a hell of a lot longer??
Probably needs a poll a question like this, but I'd have to say Genesis, give it to them over Pink Floyd and Zeppelin, as their 70's albums ('Trespass' through to 'And then there were Three') for me have the edge over Led 'Zep III' through to 'In through the Out Door'....and 'Meddle' through to 'The Wall'.
