Opera Australia has just announced that Lisa Gasteen has withdrawn from their upcoming production of Fidelio due to an ongoing neck injury. She'll be replaced as Leonora by Nicole Youl.
From the OA press release:
“We are however thrilled that Nicole Youl has accepted our invitation to perform this role at such short notice. Miss Youl has enjoyed great success in several major roles in recent years, including Cio-Cio-San in Madama Butterfly, Mimì in La bohème, Lenora in Il trovatore and earlier this year Santuzza in Cavalleria rusticana,” he said.
