At a time when opera companies are struggling to survive, it is thrilling to watch On Site Opera thrive. In spite of high ticket prices, their productions are always sold out. It would appear that the originality of their concept and the deftness of their execution would account for their success. Snagging a ticket almost guarantees a rare and unusual experience.

Mr. Einhorn kept the action flowing in the narrow acting space, flanked by seated audience members and hampered by the small size of the formal garden. Ms. Choi and Mr. Bakari dove deep into their characters, finding real weight in the moment where Murasaki finds her way to a story's end (she sends Genji into exile, and seems relieved) and redemption in the moment where the cad comes back. The singers moved and swirled in their finery, arching over a nimble score that combined the voices of eastern and western instruments to create minimal pulse, kinetic rhythms and always, strong support for the voices of the two leads.
