San Francisco Opera is following the lead of other companies such as Covent Garden, and will simulcast its first opera of this summer’s season. Tyhe broadcast will take place in an outdoor plaza. “What we want is to establish an overall image of the company as being community-friendly and very accessible, and to emphasize what I believe — which is that opera as an art form is accessible. Civic Center Plaza could accommodate as many as 12,000 to 15,000 at the outside if the circumstances were right. But I’d be happy with 5,000.”
