HOUSTON GRAND OPERA, a company well familiar with epic events and grand occasions, outdid itself at its recent Concert of Arias show and dinner.

The usual high point of the annual event — the finals of the Eleanor McCollum Competition for Young Singers, followed by an elegant dinner in the Wortham foyer — is the naming of the winners of the “American Idol”-type contest for young opera singers. But there was another announcement this year that had tongues wagging.

Indeed, after mezzo-soprano Natalie Lewis was named the first-place winner and handed a check for $10,000, HGO General Director and CEO Khori Dastoor spoke to the audience, explaining that donors Sarah and Ernest Butler had just made the largest ever single gift to the company — $22 million! In recognition of their gift, HGO’s 43-year-old, world-renowned school for young singers was renamed the Sarah and Ernest Butler Houston Grand Opera Studio.

“Decades-long HGO supporters Rita Leader and Glen Rosenbaum chaired the evening that saw record attendance and raised over $660,000 to benefit the future of the operatic art form through HGO Studio’s recruitment, nurturing, and support of world-class young artists,” added a rep for the company.

Boldface names in the crowd included Cynthia and Tony Petrello, Molly and Jim Crownover, Isabel and Danny David, Beth Madison, Kristina Sommerville, Bobbie Nau, and Grammy-winning soprano Isabel Leonard, who was among the judges for the competition.
