Performers, including several from the Albany Symphony Orchestra, will be playing popular melodies on Brookside’s grand front porch while guests relax on the spacious front lawn. On July 21, 3 p.m., the ensemble will treat visitors to a selection of toe-tapping pop favorites.  Guests are encouraged to sing and dance along. This concert is free and open to the public. Guests should bring their own lawn chairs or picnic blankets.
