New from the one-time Chicagoans who brought you The Treadmill Video and Rube Goldberg Machine is “I Won't Let You Down,” OK Go's latest foray into viral music-videography. The clip, OK Go's second in support of Hungry Ghosts (out earlier this month on Paracadute), finds the band tooling around on motorized unicycles, engaging in various acts of umbrella dance, and looking generally dapper, as per usual. It was filmed in a single shot using a multi-copter camera in Japan this summer, and was directed by Japanese filmmaker Kazuaki Seki and OK Go singer Damian Kulash. Check out the video below, and hang tight for the stunning (if slightly unbelievable) final frame.
