Sir David Pountney’s creation of a “masque” performance for our times, recycling music Purcell wrote for his, is downright good entertainment even if the plotline’s a bit incoherent.
Now that’s a virtue, if you look at the 17th century models he’s starting from. Shows with masques never were designed to have much narrative logic, and the music – even when it had words attached – could as easily fit one story as another.
