After 11 years, I have finally seen Meyerbeer’s grand opera Le Prophète.
Utterly extraordinary. It’s one of the half-dozen best operas ever, if not at the absolute pinnacle. 
You can watch the video here: https://culturebox.francetvinfo.fr/opera-classique/opera/le-prophete-de-meyerbeer-au-theatre-du-capitole-a-toulouse-271753
Setting: The Netherlands and Germany, during the 16th-century Wars of Religion.
Characters: A murderous demagogue, self-proclaimed Messiah and Son of God. His mother. His unhinged fiancee. A feudal lord. And an unholy trinity of Anabaptists.
“People of my father’s generation would rather have doubted the solar system than the supremacy of Le Prophète over all other operas” (Reynaldo Hahn).
It’s intense, with the sardonic brilliance of Euripides. (There are moments, too, like the trio bouffe in III, that look forward to Brecht.)
Meyerbeer is telling at once a small, intimate story – Fidès’s, Jean, and Berthe’s relationship – and an epic drama about tyranny, revolution, and religion; politics, mob violence, and fanaticism.
Score, of course, is superb. Highlights include the Anabaptist sermon in I; Fidès’s arias (“Ah, mon fils” in II, “Donnez pour une pauvre âme” in IV, “Ô prêtres de Baal” in IV); Jean’s dream in II; the brilliant skating ballet; the Act III finale; the magnificent soprano/mezzo duet in IV (two women sharing their grief); the Cathedral Scene; and the prison scene (aria, duet, trio). Unusual orchestral textures, melodic recitative…
The production is mod trad; there are some vaguely regie elements, but it works tremendously. Kate Aldrich is a stunning singer and actress – what a voice!; and John Osborn excellent (definitely better than McCracken). We need more grand opera!
Act I is weaker than the rest of the opera, in this production, and the Oberthal isn’t very good. From Act II – God, it’s terrific!
O sublime spectacle! Miracle. miracle du grand Prophète!
 OK, the others are Meyerbeer’s own Huguenots, Berlioz’s Benvenuto Cellini, Mussorgsky’s Boris Godunov, and Moniuszko’s Straszny dwór.
Mozart’s Don Giovanni, Offenbach’s Contes d’Hoffmann, Wagner’s Lohengrin, Halévy’s Juive, Gluck’s Iphigénie en Tauride, and Beethoven’s Fidelio also float around near the top.
