The cut was recorded for the upcoming action film 'The Last Witch Hunter' starring Vin Diesel. Evidently, Ciara is really pulling off this darker, more dramatic direction, which fits perfectly for a movie about witchcraft.
Her vocals sound exquisite over psychedelic-rock production, which actually baffles me, because a soundtrack single received better creative direction than her own album 'Jackie.' This song is something completely different from anything she's ever done in her career, and it's great that she's experimenting. This is crazy, crazy good. Check it out!
