The San Antonio Symphony has officially filed for Chapter 11 bankruptcy after a vote by the orchestra’s board. The SAS struggled with its finances all season, and laid off half its office staff last week in anticipation of the bankruptcy filing. The orchestra does not intend on shutting down completely – at least, not yet – but there is no firm timetable for a return to a normal concert schedule, and the summer months may not provide enough time for the SAS to organize a 2003-04 season.
