The enthusiastic new-music ensemble [nec]shivaree, the New England Conservatory-sponsored student sibling of Stephen Drury's cutting-edge Callithumpian Consort, transformed a programmatic hodgepodge into an entertaining, ear-opening afternoon on Sunday.
Electronic music is often a clinical laboratory of sound, but Alvin Lucier, a longtime professor at Wesleyan University and currently the subject of a yearlong NEC survey, finds its expressive core. For the 1970 work "Quasimodo the Great Lover," the sound of Ethan Wood's violin, being played in another part of the building, was passed through a series of microphones and speakers in empty rooms and hallways; by the time the music reached Brown Hall, the original tone had been largely stripped away, replaced by the collective resonance of each locale. High pitches became a percussive shimmer, low ones a metallic growl. Glissandi turned into keening wails as the overtones piled up to riveting effect.
