If you see one opera this year, make it The Exterminating Angel, ran the headline in the New York Times after the US premiere of Thomas Ades' "stunningly inventive" opera based on Luis Bunuel's surreal and satirical 1962 film El angel exterminador. Like the British composer's score, Tom Cairns' production is both spectacular and surprising. "Ades keeps the listener on edge," wrote Opera magazine, "because one never knows where his dazzling palette of possibilities will take him next."
