For their seventh performance at the Friendship Heights Village Center, the men and women of Washington Revels Maritime Voices will present a new program of songs of the sea and shore: A Voyage Across the Seven Seas. This concert follows the whaling fleets from New England to Britain, the Arctic, the Cape of Good Hope, Australia, the North Pacific, Hawaii, and back home. The program includes sea chanteys, ballads, and songs of the harbor towns.
