We heard a preview of The Flaming Lips' collaboration with Bon Iver earlier this year through some muddy audio. But now we're hearing the track, "Ashes in the Air," in its totally spaced-out and completely left-field entirety. What else should we expected from an album (Heady Fwends) that will only be released on Record Store Day (April 21) and feature blood from some of its guests in the packaging? Stream the track below.
