A contract dispute over higher health care costs and pay has left the start of the 2012-2013 season of the Chicago Symphony Orchestra up in the air.
Saturday's 8 p.m. concert with conductor Riccardo Muti was canceled less than two hours before it started because of a musicians' strike. It's the first CSO walkout since 1991.
The musicians' contract expired days ago, but they played the first concert Thursday and a free one on Friday.
CSO association president Deborah Rutter says Muti is "very, very disappointed."
No contract talks have been scheduled.
CSO members committee chairman Steve Lester says the three-year contract included a jump in health care contributions to 12 percent from 5 percent.
The union rejected the proposed contract that would have also included some pay increases.
