It features on the Side By Side EP, which also features Prass' takes on tracks by Simon & Garfunkel and Anita Barker.
Speaking about the choice of cover, Prass says: "'REALiTi' by Grimes. Four chords. Simple lyrics and melodies. I think the world of her. We worked this song out in the studio never having played it before and recorded it like three times through. I think it works although she's probably going to say 'what is this jazz shit' and hate it."
Grimes' new LP Art Angels is out now via 4AD.
