Poliça 'Tiff' (ft. Bon Iver's Justin Vernon)
If you tuned into the Coachella stream to watch Poliça this past weekend, you might have caught Bon Iver singer Justin Vernon's cameo with the Minneapolis act. Vernon also contributed vocals to Poliça's new single, "Tiff," which has now hit the web.

This simmering cut pairs shadowy synth drama with slinky R&B drum machines, and Vernon contributes some prominent backing vocals during the cinematic choruses.

The song is available on iTunes now and can be streamed below.
