East Providence singer-songwriter Allysen Callery describes her work as "quiet music for a loud world." Fair enough. However, perhaps unintentionally, when she released her album "Ghost Folk" on the day before Halloween last year, she provided a more accurate description of her sound. It IS ghost folky! Decidedly so.

Indeed, across several albums over the past decade, Callery has created a body of work that is exceedingly popular in the British Isles and Europe, where they have a lot more centuries' worth of ghosts than we do.

Callery's hushed but ultra-melodic delivery, otherworldly lyrical observations, delicate guitar figures and calculated production — which sounds as though she was playing and singing just over the hill from the doomed filmmakers in "The Blair Witch Project" — are, well, haunting.

She performs Thursday in the Tap Room at Westerly's Knickerbocker Music Center. It'll be a haunting experience in the best possible way.
