First concert was Kiss in 1978 or something, I was 8 and my Mom & Dad took me. As for the best, that is very hard to say, but it would have to be the following; Pink Floyd in 1988 (Momentary Lapse of Reason), Roger Waters in 2006 (Playing Dark Side of The Moon), Peter Gabriel in 1992 (I think), and Guns N Roses in 1988 (when they openned for Aerosmith and blew them away!).
