My wife and I will be in Firenze at the end of September/beginning of October and are interested in attending a classical concert or opera. We are the consummate novices as far as this goes so my apologies in advance if my priorities or interests seem naive or unusual. That being said, it seems that the venue itself could significantly effect the overall experience, all other things being equal. As such, I'd be interested in feedback and recommendations relative to the venues that I've found - the Auditorium al Duomo, Teatro Odeon, Chiesa di Santa Monaca, Chiesa di Orsanmichele and St. Mark's English Church.
Any additional thoughts or suggestions are most welcome. Thanks for you help, Ken
