The Music Center at Strathmore, in suburban Washington, D.C. is very nearly ready for its close-up, and if successful in its mission, it will change the face of the arts in the Baltimore-Washington corridor. “The state-of-the-art building is unique in the way it embraces art from its tiniest beginnings to its loftiest expressions. Five-year-olds learn how to hold a violin correctly; 3-year-olds can take tap dance with their mothers or fathers. When the concert hall opens next month, cellist Yo-Yo Ma will be center stage; later, Sauvion Glover will bring his thrilling kind of tap to the hall.”
