Darkness and its transition into light are the subjects of Janice Garrett and Charles Moulton's The Luminous Edge, which returns to the YBCA after an acclaimed premiere in 2014. The piece features Garrett + Moulton's six heroic dancers backed by one of their signature structures: a precise movement choir of 18 dancers — part Greek chorus, part corps de ballet — whose motions support and comment upon the action on the stage.
