Just a quick note for those of you in and around Williamstown, MA: The I/O Fest is present­ing a concert tomorrow night called “after hours” at the ’62 Center, featur­ing pieces by Trevor Gureckis, Missy Mazzoli, Sarah Snider, and my own Night Jaunt. Performed by what I assume is the first NOW Ensemble cover band ever, made up of Williams College students.
