WAY too loud. That is my major complaint. I could deal with the distortion if it was at 90 db or less. Plus, if was less loud the distortion would drop considerably. We see concerts that are not "rock" and big venues and they are amazing and very clear.
Why does rock concert sound suck?
I have been to two rock concert in the past year : Brit Floyd in Bridgeport CT and Eric Clapton at Madison Square Garden, NYC (last Monday)
For Brit Floyd I was about 40 feet form the stage and treble end was an ear-splitting distorted sound - the soprano solo on Dark Side of the Moon sounded like a chain saw running at 5x speed.
For Eric Clapton I was sitting at floor level about 20 rows behind the mixing desk - i.e., the opposite end from the stage. In this case the high top end was not so distorted, but the voices were still very harsh - seemingly a massive response peak at ~1500hz. Imagine AM radio with the treble turned up 20db.
I knew a lot of the words form the songs ahead of time of course, and just about recognized them, but otherwise the lyrics were unintelligible. The only exceptions were when he sang a quieter song - e.g., “Tears in Heaven” . Clapton moved back from the mic rather than place his mouth right next to it. Then the sound was quite listenable .
Of course managing the acoustics in such a big venue is no doubt a challenge — but does it have to be this bad?
