The best concert for me was seeing Tool at a midsize arena a few years back. Incredible sound, the visuals were wild, and the whole crowd was locked in, it honestly felt like the music just took over the room. My worst was a summer outdoor show with several bands, but a terrible rainstorm rolled in, the sound kept cutting out, and half the acts bailed. There was zero communication from the organizers. Standing out in the mud waiting for hours, only to leave disappointed, put me off those bigger festivals for a while.
