The mayor of San Antonio announced this week that he will donate $5000 from his office’s discretionary fund to the struggling San Antonio Symphony, which missed payroll last Friday and is facing more than $500,000 of immediate debt. Mayor Ed Garza also exhorted other city leaders to match his contribution, and called on corporate leaders to broaden the base of support for the ensemble. The symphony’s musicians have agreed to keep playing despite going without their paychecks, at least for the moment.
