Arnold Schoenberg, one of the most influential musical figures of the 20th century, was born in Vienna in 1874. Sony Classical is celebrating the 150th anniversary of the great composer's birth with the reissue of 20 CDs of recordings from CBS/American Columbia. The company was a pioneer in documenting Schoenberg's achievements and already demonstrated that commitment during his lifetime (he died in 1951). In 1940, with the composer conducting, Columbia Masterworks produced the first recording of one of his most captivating and revolutionary works, Pierrot lunaire; and in the 1950s and 60s, the label undertook a ground-breaking multi-volume series entitled "The Music of Arnold Schoenberg." But arguably no recordings have done more to further the cause of Schoenberg's orchestral and vocal works than those of Pierre Boulez, while none have done more to promote his chamber music than those by the Juilliard Quartet. Sony Classical now presents all of Boulez's Schoenberg for CBS/Columbia in a 13-CD box, and all of the Juilliard's in a 7-disc set.
