Piero Cappuccilli, considered one of the finest Italian baritones of his generation, lies in an advanced state of putrefaction today. He died July 12, but for reasons best known to Anthony Tommasini of the Times, that passing was not noted until today, i.e., nine days after the fact. Perhaps if Cappuccilli had achieved “international stardom” (which apparently consists of something more elusive than singing the great roles of the Italian baritone repertoire in every great opera house of the world for over 30 years), his obituary might have appeared a little more quickly. Then again, with a new production of Death in Venice about to open at Glimmerglass, Tony might have been too busy dreaming up adjectives to describe the dancer playing Tadzio (“buff?” “sleek?” “lithe?” “humpy?”)
