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 Ad�s' "stunningly inventive" opera based on Luis Bu�uel's surreal and satirical 1962 film El �ngel exterminador. Like the British composer's score, Tom Cairns' production is both spectacular and surprising. "Ad�s keeps the listener on edge," wrote Opera magazine, "because one never knows where his dazzling palette of possibilities will take him next."
