Two years ago, the San Antonio Symphony was in dire financial straits, and came perilously close to shutting down completely. Today, as the SAS launches its second full season following a tumultuous period in bankruptcy, things are looking up, and the orchestra is seeing a sharp uptick in ticket sales as well as philanthropic giving. “The symphony already has $2 million of its almost $6 million budget for the 2005-06 season,” and officials are confident that the ensemble will be able to operate without a deficit this year.
