“American Terror” is an evolving chamber opera by Hudson-based composer Jeffrey Lependorf. This work-in-progress performance is inspired by the intense 1969 debate between William F. Buckley and Noam Chomsky on US military policy in Vietnam. The opera reimagines this historic dialogue through a blend of Haydn and Scriabin’s music, offering fresh perspectives on a topic that remains highly relevant. Tickets are available on a “pay what you will” basis, with advance reservations suggested. 5pm.
