Critic and Hear and Now presenter Tom Service nominates American composer John Zorn’s Carny, a work for solo piano from 1989. The piece assembles a wide range of musical quotations and genres, juxtaposing Stockhausen and Bartok with cartoon music and boogie woogie. Author and journalist Rob Young provides some background to the work and to Zorn himself, a highly regarded improviser and producer as well as composer.
