How metal do you like your ballet? If the answer is “All the way to 11”, get a load of this. Brutal Ballet are unleashing their debut performance of Unto the Locust, based around the music of Machine Head. The band’s savage album may seem an unlikely candidate for getting the dance treatment, but its sonic textures are beautifully captured by this zeitgeist-challenging ballerina company. Rock on. Latecomers may not be admitted.
