Acclaimed percussion quartet So Percussion perform three major works for unconventional instruments including Steve Reich’s 20th century masterwork Drumming Part 1, David Lang’s The So-Called Laws of Nature, for which So Percussion built their own instruments, and Bryce Dessner of The National’s Music for Wood and Strings. Dessner’s work is performed on “chord sticks,” a cross between a hammer dulcimer and an electric guitar, created by instrument builder Aron Sanchez in collaboration with the composer.
