Lol, no way..half a dozen? Try dozens and dozens and each was unique too from Led Zeppelin 1 all the way through In Through the Out Door. They knew they were the best too. No one could do what they did as a band. Bonham was an incredible drummer. Plant was amazing as the front man. Page was a guitar god and John Paul Jones could play anything and was off the charts technically. Basically, each was the best at his craft. You can't say that about any other band. They were the greatest ever Heycal, in Gonzalez, Borg, Laver, Federer, Sampras territory. Agassi..off the radar when it comes to that. They are a modest bunch. Page about their early reviews.."I think it went over their heads"..Elvis about Zeppelin..'I wanted to meet this band that was selling more tickets than me"..The Beatles were the best band of the 1960's, while Zeppelin was the best band that emerged from the 1970's in my opinion. As far as the "experts"..
