Opera 5 opened a run of Rossini’s The Barber of Seville at the Factory Theatre last night. It’s arguably the most conventional thing Opera 5 have done. It’s a (very) mainstream piece. There was no accompanying themed food or drink (a glass of Rotsina?). There was no audience participation. There weren’t even Aria Umezawa’s characteristically minimalist touches. What there was a carefully constructed Barber for reduced forces directed by new Artistic Director Jessica Derventzis and conducted by Evan Mitchell.
