OK Go new music video: The boys are back with another crazy YouTube clip for 'I Won't Let You Down'

It doesn't get much more ambitious and creative than this

OK Go's new music video features unicycles and synchronised umbrella dancing

OK Go are back with another ambitious music video for new single "I Won't Let You Down" and, appropriately given the song's title, it does not disappoint.

The US alt-rock group's latest release, from fourth album Hungry Ghosts, has racked up almost 2.7 million YouTube views in 24 hours.

Known for their creativity ever since the video for 2006's "Here It Goes Again" featured the band dancing on treadmills and attracted over 25 million views, OK Go's newest effort sees them take to cool, self-balancing, motorised unicycles.

The five-minute video was shot in one continuous shoot and required 50 or 60 takes to get it perfect, Billboard reports.

Japanese director Morihiro Harano revealed some insider details as to how the mind-boggling project was created, including the use of a camera-equipped drone to enable birds-eye view shots of the impressive synchronised umbrella scenes.

The manual and GPS-controlled drone was taken half a mile into the air for the video's final shot, which sees more than 1,500 volunteers ride Honda scooter chairs to make up "pixels" of a staggering LED ticker-style display.

OK Go frontman Damian Kulash posted some behind-the-scenes pictures on his Instagram account while the video was being designed.
