Now it’s here, in a recording led by the omnivorous Leon Botstein, with the BBC Symphony sounding somewhat tentative and the recorded sound a little murky, but enough to convey the remarkable richness and range of color in the scoring. The sounds are late French; I want to say Franck or d’Indy, but the music is better than anything I know by either of them. It’s a fascinating score all by itself. The singing, by Lori Phillips as Ariane and Patricia Bardon in the important role as her Nurse, is just okay. The whole venture satisfies my curiosity about the work but makes me want all the more to hear it live someday.
