“Torture chamber pop.” “Darkwave jazz.” “Siren rock.” These are a few of the many attempts to describe the sound of Jaggery, an art-rock collective which weaves harp, viola, piano, contrabass, and drum kit into a universe of its own, setting the scene for “one of the most beautiful voices in modern music.” Powerful enough to harness the fiery churnings beneath a volcano as well as the ethereal light of a dying star, frontwoman Singer Mali’s voice regularly leaves listeners viscerally stunned and with goosebumps. She is flanked by a rotating lineup of musicians and instrumentation including Daniel Schubmehl’s West African approach to the drum kit, with jazz influences, Tony Leva’s funky upright bass, Rachel Jayson’s avant-classical viola, and Petaluma Vale’s glistening Celtic harp and backing vocals. This “exotic musical mobile” evokes a world of both dark, earth elements and celestial swirls ~ what Alice Coltrane’s “Journey in Satchidananda” might sound like with Bjork singing over the top of it. The band’s repertoire bridges the delicate and explosive ~ from haunting lullabies to furious, mixed-meter rants; tightly-woven compositions in odd time signatures to catharsis-inducing, barn-burning mini-epics (oft-times within the same song). Jaggery (the word comes from the dark brown, Indian sugar) has toured up and down the east coast, and has released three recordings: the 2004 in lethe ep, the 2006 full-length Polyhymnia, and 2010’s recently-released ‘Upon A Penumbra’. Jaggery’s first music video (‘O Scorpio) won their director “Most Promising New England Filmmaker 2009” at the Boston Underground Film Festival.
