Past and present become telling allies in a play about the messages of history by Jeffrey Borak
There may be a more accomplished company of performers on a Berkshire stage these days. There may even be, in aggregate, a better, more cohesive production somewhere. I don't think, however, you will find a more stimulating and intellectually challenging play than "Insurrection: Holding History," which officially opened a 3 1/2- week run Thursday at the Berkshire Theatre Festival's Unicorn Theatre.
