Yes, that sounds like the way to go. I sat out on the lawn for a concert and I may as well have stayed home and listened to a record (it was long enough ago that records would have been the medium). I also saw an opera there, inside (also ages ago), which was better in terms of noise and distractions, but I was not close enough to see the performers's faces well, so that I lost a lot of the dramatic oomph and finesse of their performances. So I think one has to sit inside, but not too far away.
