For Cathy and Peter Halstead, the co-founders of Montana’s sprawling Tippet Rise Art Center—the kind of awe-inspiring environment that requires visiting to truly experience it—the notion of creating a virtual festival, given the ongoing unknowns of Covid-19, served as an opportunity that otherwise might not have arisen. As they put it, the virus provides “an occasion to open up new and surprising experiences.” Paradoxical as it might seem, pandemic-led restrictions have in some ways resulted in expanding (digitally, anyway) this spectacular sculpture park nestled in hilly Big Sky Country. A spirit of generosity drives both Tippet Rise’s physical spaces, which have been based on a working Stillwater County ranch since 2016, and its new virtual festival, comprising films that capture classical music performances at particularly special or unusual off-site venues. (From its inception, classical music programming has been a core part of Tippet Rise, which also features sculptures and structures by artists and architects including Mark di Suvero, Alexander Calder, and Diébédo Francis Kéré.)
