The first way too loud concert I attended was Emerson, Lake, & Palmer in the early 70's. The stadium physically shook from the volume and my hearing was problematic for a week. Most of the bands I have been in have been too loud as well. Only the bands without guitarists played at reasonable volumes. Despite that, there are many guitarists who like to say the bass is too loud. A lot of the problem is that many guitarists use too much bass in their tone and it muddies things up and next thing you know, everyone is turning up and no one can hear themselves.
