The Royal Berkshire Improv Troupe (RBIT) announces today it's Winterfest Show on Saturday February 27th in North Adams at Main Street Stage. The show will begin at 7:30p.m. and tickets are $10 at the door. RBIT is a comedy improv group that has been delighting audiences with its own brand of non-scripted comedic mayhem since June of 2001. Performing a mix of theater games reminiscent of the TV show Whose Line Is It Anyway?, the group models its work on the teachings of renowned theater games/improvisation instructor Keith Johnstone. Through audience participation, RBIT's mission is to create entertaining scenes which explore the boundaries of theater improvisation.
