“Baritone Gregory Dahl, could not have captured the role of the duplicitous Iago better, and beguiled his nemesis all night long with his serpentine poison, ingratiating himself with malevolent cunning. Mr. Dahl succeeded in pulling off the greatest villain in the opera repertoire, and his Act II Credo, where he affirms his genesis as evil incarnate, was chilling. For his venomous portrayal, he was lustily booed with great approval when he came out for his final curtain call.”
