Rochester duo Everdene Holler's debut album is a curious collection of sounds. Is it drone music? Is it roots music? Delightfully, the answers are unclear, as banjo player Zora Gussow and fiddler Clara Riedlinger -- who share vocal duties -- defy expectations with six unsettling but satisfying takes on traditional folk ballads. "Undone in Sorrow" is a rustic combination of ambient nature sounds, a warm, major-chord drone, and insistent banjo playing. During the murder ballad "Matty Groves," a haunting organ drone becomes virtually atonal against the vocal harmonies. The album closes with a swirling, nearly psychedelic version of the Sacred Harp standard "Idumea," called "And Am I Born to Die" here. "Everdene Holler" is compelling outsider folk with mystical, avant-garde vibes -- the kind of music Rochester hasn't come close to hearing since Hieronymus Bogs moved to the Southwest.
