[T]his weekend a note from Mr. Amato was posted on the refrigerator in the offstage area at the company’s home in a small building on the Bowery in the East Village: he was shutting down the company after this season.
“Now, with Sally gone, I have decided that it is time for me to start a new chapter in my life,” the note read. “It has been a great 60-year run!”
In an interview on Monday, Mr. Amato said he had sold the building; the club CBGB was a neighbor for years before it, too, closed.
“I’m 88 years old, and I’m a little tired,” he said. “I have a few years left.” Mr. Amato said he might write his memoirs and wants to establish a foundation to give awards to young singers, conductors and directors. He also plans to study scores, especially Wagner’s.
Amato Opera opened originally with two goals in mind: to present entertaining opera at popular prices, and to give singers a stage on which to gain much-needed experience in full-length productions. The early company utilized students from Tony Amato's opera classes. ... Early performances were free because union regulations would not allow them to charge admission. Contributions were requested during intermission. Tony Amato had invested his own money to get the company started. At 319 Bowery, when admission could be charged, tickets were $1.20 an reserved seats, $1.80. In 1975, 15 years later, ticket prices were only $3-4 a performances. Today, at only $23 for an orchestra seat, ticket prices are still a fraction of what is charged at other opera houses. Amato is believed to be the only self-sustaining opera house in the United States. ... The Amato Opera is often referred to as a "mom and pop" operation.
