Jaggery is a Boston/New York-based collective that works the dark edge of a genre-defying musical style (darkwave jazz?). They bring to mind a more classical, organic, avant-jazz oriented Cocteau Twins, or a “white witch” counter to the haunting Diamanda Galas. Front-woman Mali Sastri conjures up emotion and atmosphere which can only be weighed on a global scale. Her voice can be a leaf floating in the wind, and then become an Earth-shaking, Everest-sized volcano. Yet delicate or explosive, it’s always magnificent, captivating and sustained by a gorgeous tapestry woven by Tony Leva on soulful stand-up bass, Daniel Schubmehl on organic, jazz-influenced percussion and drums, and Petaluma Vale on dream-like Celtic harp.
