On the 150th anniversary of the birth of Charles Ives - acclaimed by his champion Leonard Bernstein as the "first great American composer", who, "all alone in his Connecticut barn, created his own private musical revolution" - Sony Classical presents the most authoritative recording collection ever released of works by this eccentric, prophetic genius. The 5-CD box set Charles Ives - The Anniversary Edition is a unique and provocative introduction only released previously 50 years ago on LP by Columbia Masterworks under the art direction of Henrietta Condak to celebrate Ives's centenary. The first disc examines "The Many Faces of Charles Ives" through eight diverse works recorded between 1964 and 1970: Bernstein conducts the New York Philharmonic in The Fourth of July and The Unanswered Question; General William Booth Enters into Heaven, one of Ives's towering achievements, and The Circus Band are performed by the Gregg Smith Singers; baritone Thomas Stewart sings the moving song In Flanders Fields; organist E. Power Biggs plays Ives's Variations on "America"; composer Gunther Schuller conducts The Pond for chamber orchestra; and the Largo cantabile Hymn is performed by the New York String Quartet and double bass player Alvin Brehm. CD 2, "The Celestial Country", offers Ives's early cantata by that name, composed in 1897-99 for his conservative Yale composition teacher Horatio Parker. It is sung by the Gregg Smith Singers (accompanied by the Columbia Chamber Orchestra), who also perform arrangements of four of Ives's most powerful patriotic songs with the American Symphony Orchestra and Leopold Stokowski conducting. "The Things Our Fathers Loved", CD 3, contains 25 of Ives's songs, delivered by the soprano Helen Boatwright, who specialized in American song. She is partnered by John Kirkpatrick, who studied and worked closely with Ives and is still regarded as the most authoritative interpreter of his piano music. Gramophone in 1974 praised this famous recording as "the finest selection ever to appear" on LP of "what may well turn out to be considered his most important, characteristic and consistently inspired body of music."
