Wrekmeister Harmonies, led by musician and composer JR Robinson, is an experimental music collective based in Chicago, Illinois, United States. Named after the Béla Tarr movie Werckmeister Harmonies, it combines elements of drone music, serialism, post-rock, and heavy metal. Wrekmeister Harmonies typically performs a single composition, often almost an hour in length, beginning with a slow build, shifting into a cathartic middle section, concluding with either a peaceful or disquieting resolution.
