Signed and inscribed on the first blank leaf to the important composer's frequent collaborator, violinist Paul Zukofsky: "for Paul Zukofsky, at the beginning with pleasure, John Cage, February 1977." 217 pp. Softcover. Wrappers somewhat faded, overall fine. 8 x 9 inches (20.4 x 23.2 cm).

M was Cage's third full-length book, after Silence: Lectures and Writings and A Year from Monday. Henahan, writing for The New York Times Book Review, contrasted the "uncollectable and unpreservable, gaily but deliberately writ on water" form of his music with "slight chance of outliving him by much" to the solid permanence of his writing, including M.

American violinist and conductor Paul Zukofsky was known for his work in the field of contemporary music. Born in Brooklyn, New York, Zukofsky was the only child of the American Objectivist poet Louis Zukofsky and Celia Thaew Zukofsky, a musician and composer. He began performing at an early age and was soon drawn to modern music, especially to the possibilities of extended techniques on the violin. Over the course of his career, he collaborated with composers including Milton Babbitt, John Cage, Elliott Carter, George Crumb, Morton Feldman, Philip Glass, Peter Mennin, Krzysztof Penderecki, Roger Sessions, Charles Wuorinen, and Iannis Xenakis. He gave world premieres of concertos by Robert Sessions (for violin, cello and orchestra), Charles Wuorinen (for amplified violin and orchestra), Morton Feldman (for violin and orchestra), Phillip Glass, and the Scottish composer Iain Hamilton, among others.
