For OK Go's latest video, they took on a new challenge: Math. Frontman Damian Kulash and bassist Tim Norwind sat down with Mashable to discuss the video for "This One Moment," in which hundreds of small events take place in a matter of seconds thanks to a small army of robotic arms, several cameras to capture it all and some very intense planning. "I have this spreadsheet that is massive that I was working on for a month, and sometimes I would look at it and it would not be numbers anymore, it was just squiggles," says Kulash, who directed the video. "There were times that my brain just cracked." "I don't understand a goddamn thing on that spreadsheet," Norwind laughs, but he's willing to take credit for having the most challenging role on the actual shoot. The rhythm required to lip sync, operate a flip book and then soar through the air as a human canvas in such a precise timeline is the sort of thing a bassist is uniquely qualified for.
