Rising-star composer-vocalist Kate Soper is having a good year. It kicked off with the release of her lyrical and abrasive album, Voices from the Killing Jar. And it continues this week with the debut of her latest stage work: a three-act meditation on Egyptian themes (partly inspired by the works of Amelia Edwards). Fittingly enough, it's being presented in the gallery of the Met that houses the Temple of Dendur. Alan Pierson leads the cutting-edge instrumentalists of Alarm Will Sound. Nigel Maister directs.
