“Imagine sound on a spectrum,” says Zosha Di Castri, “moving fluidly between abstract soundscapes, gestural outbursts, and referential echoes of musics half-remembered.” Pianists, percussionists, and vocalists come together alongside electronics to explore the rich gamut of Di Castri’s work. Two premiere performances—including Near Mute Force for members of both ensembles—are among the evening’s repertoire.
