Book excerpt: This is the first and only scholarly book to date on George Rochberg (b. 1918), the pre-eminent post-WWII American composer and essayist. It was compiled with his assistance and gathers into one volume previously scattered and hard-to-find material by and about the composer. Included are traditional types of scholarly information on Rochberg, e.g., his WORKS (date of composition, publisher, timing, commission, premiere, instrumentation, program notes by the composer, etc.), DISCOGRAPHY, BIOGRAPHY (a chronological listing of his compositions and the major events of his life), AUTOGRAPH MANUSCRIPTS & DOCUMENTS (housed in public collections/libraries), TEXTS (used in the works with voice), and BIBLIOGRAPHY (books, articles, and reviews by and a bout Rochberg). This is an essential guide for any performer, scholar, critic, or student of George Rochberg's music.
