The singer is seen performing to a room of clones in the clip, which he released via his official YouTube page today (June 11).
The track serves as the latest single from the former Supergrass singer's first solo album Here Come the Bombs, which is out now.
Coombes previously described the LP as "11 little sonic explosions", adding: "There's all kinds of references from space travel to fatherhood to love to war, exploring different things."
The star recently completed two UK headline shows as well as a slot at Camden Crawl.
