Ethan Iverson, with whom I am perpetrating An Evening of Spooky Modern Music Tuesday next, has announced the lineup of twentieth-century piano excerpts for the show, with edifying, amusing, and altogether richly learned comments. He includes a provocative remix of Milton Babbitt's Semi-Simple Variations, with backing rhythms by Bad Plus drummer David King. The possibility is raised of a full-bore Bad Plus rendition of Babbitt. We'll see if this materializes.
