My copy arrived too and I've only delved into the first act as yet and while it's obviously very well-crafted, nothing has really leapt out at me yet. Perhaps it will take time. As Alan says, the booklet - well, book really - is very thorough. Alongside a couple of good essays, there are about a dozen pages of musical analysis with excerpts from the score. It's similar to the packages put together by Bru Zane, but the in-depth analysis is something I've not seen before. It helps identify the motifs Erlanger uses, but as Alan also points out, you'll be looking in vain for the big tune. Nevertheless, it's great to have another rare French opera from this era. Perhaps we might dare hope for some more Erlanger - or Bruneau or Aubert or Dupont's rather fine Antar?
