South London's Halls teams up once again with Sebastian Nevols of BBC's Blue Planet on the video for "White Chalk." Like the haunting track from his forthcoming full-length debut, Ark, the visuals explore negative space. Filmed on a sparely lit stage, with the choir sometimes bathed in glorious, golden light, the song's stark pauses are accented with dramatic moments of total darkness,. Halls himself sits at his keyboard, casting long shadows and somberly plucking out chords. Ark drops October 15th via No Pain In Pop.
