In 1854, Wagner wrote an arrangement of the overture to Gluck’s Iphigenie in Aulis, adding a new ending of his own. ATMA offers the first-ever recording of Wagner’s original, discovered in the Zentralbibliothek Zürich in the late 1990s. The Orchestre Symphonique Bienne delivers two more gems: a studio recording of Siegfried-Idyll in its original version for chamber orchestra and excerpts of the first ever video recording of the work in the venue of its world première, the Tribschen villa. In recent years, the Orchestre Symphonique Bienne has specialized in the repertoire of the Viennese Classics and the early Romantics.
