True, people have to be responsible for their own health. But most people don't know that they are in an ear damaging situation nor do they carry a SPL meter with them. So if we are to play loud, should we warn them so they know?
Sometimes we play for dinner sets where people want to talk. They also listen. That's OK.
Sometimes we play where people want to dance. That's OK.
Sometimes we play on stage in a concert and actually put on a themed sho. That's OK too.
People use music in different ways, and since I do this for a living, it's up to me to supply them with their needs at the time.
And even in the concert situation, I don't hit the first row louder than 85dba.
It's just about being kind and caring not to injure the people who come for a good time.
