As Ben Ratliff wrote in the New York Times, the aggressive and sublime first album by the band Elder Ones, Holy Science, is a kind of gauge for how strong and flexible the scene of young musicians in New York's improvised and experimental music world can be. At the center of it are drones and phonemes. The group's leader, the 30-year-old composer and singer Amirtha Kidambi, holds forth behind a harmonium, the small keyboard instrument with hand-pumped bellows; it's commonly used in bhajan, the Indian devotional-singing tradition that was central to her musical experience while growing up in a South Indian family. Kidambi formally trained in classical music, singing works by avant-gardists including Nono and Stockhausen, but the pull of free jazz and Alice Coltrane drew her toward a different path. The influence of both Alice and John Coltrane is especially apparent on the new album, as is her work with composer and saxophonist Darius Jones, and her study of Carnatic music.
