I'm a proud native of Philly(-delphia), so I'm lucky to have the Philadelphia Orchestra as a "house band", as it were. But I recently went to a small recital with a local (northwest Philly) choral group who sung Beethoven's Missa Solemnis with a local orchestra- and it was really good. I was particularly surprised to see a small neighborhood group perform a work of that scale- which made me curious about local groups in other parts of the world.
So, what local groups are in your area (excluding "city orchestras", like the Philly Orc, the Minneapolis Orc, etc) and what kind of repertoire do they perform? Are there good neighborhood opera companies in your area? I'd like to hear about some other local scenes.
