The French countertenor-turned-maestro Raphaël Pichon chooses programs for his superb period ensemble and chorus Pygmalion the way masters of Ikebana compose flower arrangements, placing each perfect bloom to subtle yet poetically charged advantage. This time, the bill features excerpts from Ambroise Thomas’s opera Hamlet as well as Hector Berlioz’s funeral march for the final scene of Shakespeare’s tragedy, a movement from the choral suite Tristia. The Gabriel Fauré Requiem, finally, brings the evening to a musically logical close. The vocalists are Pichon’s wife, the exquisite soprano Sabine Devieilhe, and the baritone Stéphane Degout, their frequent collaborator. Though the solos aren’t listed, Thomas’s moody setting of Hamlet’s “To be or not to be” (Être ou ne pas être) and Ophelia’s marvelous coloratura Mad Scene, with its insinuating Arabian Nights inflections, are sure to figure in the mix. —Matthew Gurewitsch
