One of the best live gigs I saw was Led Zeppelin in London 1972 or 3 I think. I loved the whole experience and Robert plant has such an encredible voice. I sort of went off zep a bit during the later years. But their first 4 years for me was defenitly their years for live gigs. So powerful. I can still feel John Bonham bass drum in the pit of my stomach during communication breakdown.
