Say what you will about OK Go’s music, but the band has a knack for attention-getting uses of technology in its videos — and its latest project only drives that point home. The new “I Won’t Let You Down” promo has band members performing dance numbers on Honda’s UNI-CUB robot stools, letting them bust moves that aren’t possible with legpower alone. And that’s only part of the technology involved. Director Morihiro Harano uses an octocopter drone to capture dramatic pull-out shots, while a legion of Japanese schoolgirls creates giant pixel art by dancing in Busby Berkeley-style routines. Is it over the top? You bet, but it’s doubtful you’ll forget this mechanical extravagance any time soon.
