Gas masks, electro-shock units, levitating girls — and we’ve just scraped the surface of Doomtree’s clip for “Beacon.” The video for the No Kings track is a steampunk-noir chiller, rife with grainy shutter-shots and aviator goggles. Dessa, the Minneapolis rap collective’s leading lady, does cool floating tricks dressed in Victorian attire, while steam billows around the rest of the group. A steampunk rap video sounds horrible in theory — can you imagine a monocle-wearing Waka Flocka rapping on a Zeppelin? — but Doomtree proves that sci-fi and hip-hop make surprisingly good artistic bedfellows.
