Today’s “indie opera” outfits are making do with less money than what even our country’s regional-level companies enjoy, so it’s no surprise that chamber-size realizations are often necessary.

“Over his 14-year directorship, Oundjian grew to be the energetic face of a revitalized TSO, steering the Orchestra out of deep financial ruin in the process – according to the TSO’s annual reports available from the 2006/07 season onwards, the organization ran yearly operational surpluses except for the 2009/10, 2011/12, and 2012/13 seasons. While the move isn’t surprising at all, the other news is that Sir Andrew Davis will return to fill in as Interim Artistic Director through 2020 until a permanent successor is found.”
