Facemasks and a lot of cameras helped the symphony come to life this spring. "It happened again last night," says Don Hamilton, a hint of something close to rapture in his voice. "There was a 30-piece orchestra onstage, and I was — and this is a word often abused — literally the only other person in the room. I'm all alone in the Fox Theater, a building with a capacity of 1,700, and live musicians are playing Mahler as if it's for me." Hamilton's private concert experience stems from the fact that he's been overseeing the recording process for the Spokane Symphony's first-ever streaming concert series, itself a product of the COVID-19 restrictions that continue to limit the size of indoor gatherings. Those same restrictions obviously affect film crews, too, which is why Hamilton has lately found himself enjoying full-blown performances for an audience of one.
