My church choir director (I’m in the choir) is an instructor at a local community college. She plays a woodwind instrument herself. Her program has three concerts a school year, and she also plays in other groups, such as occasionally with other faculty. I was at a concert last night that featured a choral group as well as some faculty from her school. It was very good and free for me, since she invited a few of us and paid for our $20 tickets.
But the community college concerts are free. The Halloween one is very good.
