The expanded new edition includes the parts of Offenbach's probably most popular work that have become accessible since 1999. The quartet La Barque à Caron (Charon's Boat), the entr'acte for scene 3 as well as two versions of the finale of scene 3 and finally the couplets of Amphitrite have been rescued from oblivion - numbers of both musical and scenic relevance which complete the widely performed, award-winning edition of Orphée aux Enfers as part of the Offenbach Edition Keck. Access to the critical report and further text and material is facilitated by replacing the previously separate CD-ROM supplement with online links. Indispensable for study and performance!
