The orchestra also announced that it had canceled four Young People's Concerts scheduled for March 1 and 2.
The SLSO has now canceled 18 subscription concerts since musicians rejected a contract offer and the work stoppage—called a strike by management and a lockout by musicians—began on January 3.
The two sides met last week for the first time since concerts came to a halt, and apparently nearly came to an agreement in a marathon session on February 17. But a last-minute disagreement, blamed by each side on the other, scuttled the deal. No further talks are scheduled.
