This psychedelic Flaming Lips ballad features typically spaced-out lyrics such as light bugs glowing "like tiny spaceships in a row." There is also a reference to orange flowers blooming "into Saturn, Jupiter, the moon," but there's no mention of the titular planet Neptune.
Kacey Musgraves joins The Flaming Lips on the track, crooning harmony vocals alongside singer Wayne Coyne. Musgraves is a big fan of the psych legends; the country star covered their Yoshimi classic "Do You Realize??" at Bonnaroo 2019.
According to Coyne, the song originated with "a very evocative series of melodies" that multi-instrumentalist Steven Drozd bought to the table. They suggested to the Flaming Lips frontman "an older, mature mind reflecting back into a journey from younger innocence then starting to learn and understand and keeps going into the panic of becoming one with the world."
Inspired, Coyne came up with a collection of "blissful, innocent, psychedelic experiences" created from discussions between him, Drozd and Musgraves.
The mournful video features Wayne Coyne draped in an American flag. He wanders around a burning field inside the huge plastic bubble he uses to walk over concert audiences.
