It's been a while, but OK Go are back for their first music video-cum-visual art project in several years - seemingly prompted by Donald Trump's return to power.

The band's frontman Damian Kulash co-directs the visual for A Stone Only Rolls Downhill with Chris Buongiorno, which begins with a title (in a familiar font) simply stating: 64 Videos on 64 Phones. It then presents the four members of OK Go through a varying, increasingly complex arrangement of phone screens, moving from phone to phone , or have a number of screens composite part or all of the image, and employing an escalating number of phones for ever-greater and ingenious compositions, also involving hand-based choreography.

In other words, it's very clever. Not as spectacular as some previous outings, but just as magical and distinctively OK Go-like as ever. There's a peek behind the scenes, on how this very complex job was created and project managed in the BTS video. 

However, unlike their previous videos the visual is also a poignant counterpoint to a lyric that's akin to a person gently breaking some very bad news: 'I wish I could tell you it'll all be just fine.' It's pretty clear what that refers to.

"We invested all this time and effort into this so that you could have three minutes of wow in your day and a real sense of joy about other humans in the world," Kulash expains in the BTS. "That's a very precious commodity now." 

OK Go have responded to the world going to shit in a very OK Go way.
