Here's a performance of Opera Nova at Billingham Theatre Upstairs on 7th July 2012.
Opera Nova is a local choral group (local to the North East of England) and the singers are remarkably talented. They are a positive joy to listen to. The performances are dramatized which considerably adds to the fun.
My wife once dragged me off to see opera at the Met in New York. Trust me, Opera Nova is (a) more fun and (b) a lot cheaper than the Met. On the other hand, the Met did have rather glorious scenery.
