Having made some of the most memorable music videos of the modern era, cult indie rockers Ok Go have done it again with their new single ‘Upside Down & Inside Out’, which is the first music video to be shot in zero gravity.

Reuniting with director Trish Sie, who was behind their memorable 2006 single ‘Here It Goes Again’ which was filmed on synchronised treadmills, the Chicago four-piece filmed their new video during eight “parabolic” flights in the skies above Russia.

Working with S7 Airlines, the biggest domestic carrier in the country, they were flown upside down for short periods, making them effectively weightless, with water bombs filled with dyed liquids exploding around them.

“Hello, Dear Ones. Please enjoy our new video for ‘Upside Down & Inside Out’,” they wrote on Thursday (February 11th) via their official Facebook page when they dropped the incredible video. “A million thanks to S7 Airlines. #GravitysJustAHabit.”

The video, which has already been viewed more than 23 million times, opens with the words: “What you are about to see is real. We shot this in zero gravity, in an actual plane, in the sky. There are no wires or green screen.”

Lead singer Damian Kulash explained the group’s motivation for filming the ground-breaking video. “It was nearly a decade ago that the world started buzzing about commercial space travel and exploration,” he said. “It dawned on me that soon enough people will be making art in space. So for years, we've been looking for the opportunity to make a weightless video. I mean, what could be more thrilling than astronaut training?”

Trish Sie also spoke about the experience, revealing that the II-76 MDK plane in which it was shot could only achieve weightlessness for 27 seconds at a time. “Because we wanted the video to be a single, uninterrupted routine, we shot continuously over the course of eight consecutive weightless periods, which took about 45 minutes, total.”
