I almost always wear earplugs at concerts now. I've experimented with several brands - still looking for one I can absolutely say is the one. Last year at the John 5 show, we were standing by the mixing board. Some yahoo kept coming over and telling the sound guy to turn it up. The sound guy - to his credit - finally turned to the guy and said, 'It sounds perfect, why would I change anything?' I talked to him a bit after the show and told him he was dead on - the sound was great, and it wasn't overpowering. Same at King Crimson this year.
