The third annual Phoenicia International Festival of the Voice opens on August 2 with an “operatic comedy.” Divas Unleashed brings the spirit of Saturday Night Live to a rarefied artform, shaking things up with slapstick and lots of action, including some swordfighting. Festival co-founder Maria Todaro wrote the script with Michelle Jennings, and the two sopranos also star in the spoof, singing the ten most famous arias in opera history in high heels and gowns while one bangs the head of the other against the piano.
