Heard the Back Bay Chorale do a mix of Italian music "for cathedral, concert hall, and opera house." I was particularly struck by the Rossini liturgical piece O salutaris Hostia, clearly dramatic, yet spiritual. I also enjoyed the other Rossini pieces from Péchés de vielillesse ("Sins of Old Age"), especially the Toast for the New Year -- so light and festive. It was also nice to sit with friends (one of whom I thought would be singing) and listen to other folks I know singing.
