I see ppl that you were on many good concerts with huge artists. I was on maybe 3 or 4 concerts in whole my life. You haven't heard about those artits cause there are from Poland, but the best concert I ever been? It was 1 week ago, at my university juve (students festine event). Band was called Fisz & Emade (aka Tworzywo Sztuczne)., not commercial band or something. There were also funny comics. I entered into huge ball called Ultraball made of plastic etc. some funny vehicles.
