We've already heard the Grimes collab/title track from Blood Diamonds' Phone Sex single, and now 4AD has dropped the b-side, "Ritual." Inspired by a "cyborg-ish desire to be human," the trance-y pop anthem contains what the label calls Blood Diamonds' "distinctive, gender-warped vocals," which, as it turns out, also sound suspiciously like Grimes. The Phone Sex 12" is out next week on transparent pink vinyl, with cover art (pictured above) by Elite Gymnastics.
