Cecil Frena and Alex Fischer's video for Purity Ring's heartsigh is a performance video with an extra little bit of magic thrown in.

Employing the stage lighting design of the band's latest tour, we witness Purity Ring's otherworldly gig atmosphere, where Corin Roddick plays glowing crystals and singer Megan James is lit up by strobe lights while suspended in the air.

The trance-inducing video goes back and forth between stage show and the singer's levitating sorcery, complete with winding camera moves and an audience of faceless dancers with long ribonned sleeves performing an evocative dance.
