Oh, look at this!—what a creative, generous response to the pandemic! Cellist Yo-Yo Ma and pianist Emmanuel Ax played pop-up concerts for essential workers at various sites in Pittsfield, Mass., on Tuesday, Sept. 1, 2020. That remarkable stage traveling stage was designed and built by artist Mike Rousseau. It put me in mind of Sylvia Linsteadt's Tatterdemalion or the folks at Hedgespoken. Imagine traveling players performing A Midsummer Night's Dream within its confines. Or shrink it to twig-fairy size for a sly tale. Or send it into a strange future. And meanwhile join these world-class artists in thanking the workers who are somehow keeping our world together.
