Initially conceived as a multimedia chamber opera about early 20th century renaissance woman Isabelle Eberhardt, this piece proves its mettle as an audio-only experience. Composer Missy Mazzoli has a post-minimalist streak, which means she's quick with a memorable hook (try the piano line on "Interlude," and the bass clarinet that opens "The world within me is too small"). But she can also plot a dramatic arc within a movement, with moments of spareness leading to clamorings. The NOW Ensemble was literally born to play music like this. An important document of the New New York classical scene.
