Allow me to paint a picture for you: It’s 2012, and an amateur Spanish painter named Cecilia Giménez has botched a restoration of a sacred “Ecce Homo” fresco so badly, that it makes international news. Though this might sound like an unlikely plot for an opera, Andrew Flack and Paul Fowler saw the potential, and the result is the world premiere of a rollicking, irreverent, and oh-so-witty comedy. Humanizing Giménez, the opera is a study in the power of internet memes, the unexpected twists and turns of life, and the economic wellspring that is tourism in the social media age — all in a soaring libretto.
