When the Baltimore Symphony announced that it would play an ambitious season of concerts at the newly constructed Strathmore Music Center in suburban Washington, D.C., in addition to its home schedule in Baltimore, critics noted that the move was a direct incursion into the National Symphony’s territory, and questioned whether there was enough consumer interest to support the move. Apparently, there isn’t. Ticket sales for many BSO shows at Strathmore have been sluggish, and with the BSO running a deficit, the orchestra has made the decision to cut back on its visits to Washington. Twelve concerts have been scrapped in the current season alone, with more cuts possible next year. The good news is that the BSO’s traditional classical concerts at Strathmore are drawing well.
