La Cieca, who only yesterday was perpendicular hanging from a cable car, has been annoying San Francisco natives this week by humming the immortal theme song of that city by the bay while strolling her streets. (That’s the Jeanette MacDonald song, not the Tony Bennett number, but that’s not the point here.) Providing a welcome break to the incessant “beat my feet up and down Market Street” was a visit to the Berkeley Opera’s production of a brand new musical theater piece, Chrysalis, with music by Clark Suprynowicz and libretto by John O’Keefe. In mood and style, it’s Lady in the Dark meets Trouble in Tahiti (smart and jazzy) with a Twilight Zone plot oncerning cosmetic surgery. Mezzo Buffy Baggott does a dazzling diva turn as a driven cosmetics CEO. Our publisher JJ will write about the piece in detail for musicalamerica.com early next week, but, in the meantime, La Cieca urges the Bay area segment of her cher public to jump on the BART train to the Berkeley Opera and take in this entertaining and thought-provovking new work. Remaining performances are Friday the 28th and Sunday the 30th.
