A Valentine’s Day program of Love and Loss will be offered for the planned return to the Brunswick High School auditorium. The opening strains of the February 14 concert might be surprising, but soon concert goers will be swept up in the “Siren Sounds Waltz.” This clever work by Deutscher transforms the ugly sounds of street life into beautiful music. Then it’s off to Catfish Row and many of the best-known songs from Gershwin’s beloved opera, Porgy and Bess, as arranged by Robert Russel Bennett. Selections from Prokofiev’s “Romeo and Juliet” provide a fitting close to an evening of beauty, romance, struggle, and loss.
