New York: Southern Music Publishing Co., Inc. . First Trade Edition. Inscribed mostly in French "For Nicolas Nabokov ami de longtemps et frère d'armes son [sic] sincère admiration/ Virgil Thomson/ le 15 janvier de [sic] 1976" on the front flyleaf. First trade edition of the full score (there was also a limited/signed edition of this that came in a slipcase, which had the same softcover binding). Nicolas Nabokov (1903-1978) - first cousin of the more famous Vladimir - was an important Russian musical emigre who was associated in the 1920's with Diaghilev and the Ballets Russes, and was also a composer of ballets and operas (Rasputin's End, 1958 and Love's Labor's Lost, 1971). Thomson (1896-1989) was an important American composer who did much to forge a distinctly American "sound", and who mentored Paul Bowles, Ned Rorem, and Leonard Bernstein. He wrote 2 operas in the 1920's with Gertrude Stein - Four Saints in Three Acts and The Mother of Us All, plus ballets and film music. Lord Byron was his third and final opera. Large 4to (9"x12") wrappers in card cover illustrated by (future pop) artist Robert Indiana. Thomson was also a prolific music critic, whose collected reviews are just now appearing in the Library of America series. 294 pages. A very nice association between two contemporary opera composers. Lightly bumped at heel of spine, shallow internal crease front cover, else near-fine in original illustrated wrappers.
