Light and darkness are intertwined. Projectors cast rays on swaying shadows, momentarily revealing silhouettes, then promptly fade and drown them in twilight, only to repeat the cycle a fraction of a second later. Low frequencies relentlessly batter bodies with deafening cannonades of percussive patterns. The sound transmutes through every waking moment with no warning of forthcoming alterations. The boundary between trepidation and anticipation is erased — brace yourself for impact.
