A rainy summer evening at Caramoor in Katonah, New York becomes a Contamination Observation as Punch Brothers deliver an unforgettable performance of breathtaking musicianship, rich harmonies, and previews from their forthcoming album. From wandering the historic Caramoor grounds and enjoying barbecue from Bark & Brine to reflecting on mastery, sufficiency, and the quiet generosity of great artists, this field note explores why some concerts linger long after the final note has faded.
