Counter-Productions Theatre Company bucks the trend of holiday fare with a free staged reading of new play Choke, written by Blue Man Group alumnus Matt Greene. The drama centers around four men in a Mixed Martial Arts gym: Marcus “The Reaper” Dillon, a former fighter sidelined by a subdural hematoma; his mentor/gym owner; a younger fighter he reluctantly starts coaching; and a local drug dealer whose stash ominously goes missing. It’s the first of two staged readings that Counter-Productions has planned for the winter.
