Last night I dropped by WKNO's live preview of A Midsummer Night's Dream, a new a cappella opera by Michael Ching, who recently stepped down as Opera Memphis's General Manager. All I can say: Wow! Ching's score, written entirely for the human voice, does away with all traditional orchestration. Created in conjunction with Memphis's superb a cappella chorus DeltaCappella, it's A Midsummer Night's Dream as Bobby McFerrin might have imagined it. Given the enduring popularity of the source material, if the rest of the opera is as light and tasty as the preview samples, this show should have some serious legs. Don't take my word for it, have a listen.
