We've been taking our kids to outdoor concerts since they were babies -- as a result, they both love music.
Neither have hearing loss from it.
Of course, we always sit on the lawn far away from the stage -- I actually prefer it that way. The venue where we take them allows you to bring in your own food/drink, so we usually do a picnic basket, that coupled with a blanket and a frisbee for the kids pre show, and we're good to go.
