When I heard that Opera San Jose’s “The Marriage of Figaro,” a Mozart masterpiece, would be set in India of the Victorian times, it was impossible to not be a wee bit skeptical. It seemed like an incongruous mingle-mangle, like the new Princess of Wales getting her hair styled, in a Pizza Hut T-shirt, no less, at Cupertino’s Supercuts. The opportunity to watch this latest production by Opera San Jose presented itself, and I went to Downtown San Jose’s California Theatre on opening night. While watching “Figaro,” I found one too many disparate details of India fused together in somewhat dissonant ways. Yet, the overall effect was charming and visually captivating.
