The rare SPA recordings and private audio documents, 1943-1958. Composer George Antheil (1900-1959) is most remembered for his mechanistic piano music hailed by 1920s Paris, but by 1948, when he’d become the third most-played American-born composer of orchestral music, his style reflected a more emotional, more mature personality. This centennial collection highlights selections from Antheil’s later “neo-romantic” period and includes the only recordings of Antheil himself at the piano. A 60-page booklet by Charles Amirkhanian, illustrated with previously unpublished photos, accompanies this 2-CD set.
