[Dallas Opera, 28 September 2011]
DALLAS, SEPTEMBER 28, 2011 - The Dallas Opera, after taking the difficult step last July of cancelling one of the five mainstage productions of the 2011-2012 “Tragic Obsessions” Season, in order to preserve cash and accelerate the company’s quest for financial balance, is now meeting key milestones in its turnaround plan. This is credited to both significant cost reductions and an outpouring of generous financial support for the company in the wake of that cancellation.
