On Circles, Lori Scacco integrates her diverse background-as an architectural student, classically trained pianist, member of the Savath & Savalas live band and Seely alumn-into her take on environmental ambient jazz. A cursory listen may suggest these delicate compositions to be benign, even slight. But coursing through Circles‘ open spaces lies a strong, uplifting emotional tug. If Circles lapses into Chicago post-rock autopilot in its weaker moments, it also reveals a voice on the verge of realizing itself.
