Classical music website slippeddisc.com reported that the operagoers in attendance were understanding of Keenlyside's difficulties: "the audience gave Simon minutes of the most rapturous applause after an amazingly intense cortigiani. When Meyer paid tribute to him in front of the curtain, the audience erupted in a prolonged, intense applause," a member of the production team told the site.
It is not clear if Keenlyside will be able to resume his role in the opera at its next scheduled performance on Tuesday. The opera is being managed by the artistic director of the Dutch National Opera Pierre Audi, and conducted by South Korean pianist Myung-Whun Chung. Saturday's premiere was the long-awaited first new production of Rigoletto in the Viennese National Opera in more than 30 years.
