Since we started over ten years ago doing our summer workshop for choral singers  from around the country at Sonoma State University, we have watched the conclusion of construction on the Green Center ( pretty much a duplicate of Ozawa Hall at Tanglewood where we'll be in July) and since its opening enjoyed singing the final concert with the participants  in the hall.  We were presented in concert there tonight for a very friendly and amusable audience who were, we suspect, pretty familiar with us.   Happy to be home after the traditionally long spring tour for a few days of r and r and figuring out what to pack for Bolivia.
