An incident on August 8, 2009, at the Monadnock Music concert series in Peterborough, New Hampshire, has forced organizers to hire security guards for their future concerts. A man identified as William Kostric was seen with a handgun strapped to his thigh and a sign that read, “It is time to silence the belltree of Marxism.” Kostric’s sign was likely referring to “Song and Dance,” a 1976 piece by the Marxist composer, Frederic Rzewski. “Song and Dance” was part of a percussion-oriented concert entitled “On the Beaten Path.”
