The return of Jack Sibley's music project North Downs after a four-year hiatus is heralded with the psych-drenched electronica of Here Come Butterflies and an absorbing visual interpretation directed by Jake Mavity, featuring Farah Ashraf as a girl undergoing a remarkable transformation.

In the video, the girl's commonplace life on a canalside walk is interrupted by visions, and then a room of TVs with distorted images of Sibley performing, and another version of herself, trapped in the TV, wearing a green party dress. When 'real' Farah connects with the girl in the TV it triggers a change, where she becomes that other version of herself, within an enclosed mirror-lined space - until she is ready to emerge from the cocoon.

Sibley's brief for Mavity was to represent a butterfly's transformation within its chrysalis - in the song he draws a parallel between humanity's incessant drive for technological advancement with the instinct of a caterpillar building its cocoon - and Mavity's response was to take a strictly in-camera, analogue approach, mostly eschewing digital VFX in favour of practical effects.

Most crucially he built a real, mirror-lined 'cocoon' space, in an LED studio, in which he had enclosed Ashraf. Previously shot footage was played onto the LED studio floor, reflecting up on to the mirrors in the cocoon surrounding Ashraf.

“Jack approached me with not just the banger that is Here Come Butterflies but also an intriguing creative vision too. There seemed to be a commonality with the transformation we underwent everyday via our online, digital lives.

"So the question was how best to explore what happened inside a butterfly’s cocoon during metamorphosis? How could we peel back the skin and expose the flesh beneath.

“We built a 3 metre high, mirrored cocoon and then projected imagery we’d shot from an LED floor, creating a kaleidoscopic effect. We also played footage of North Downs performing through various analogue filters, adding effects and pulses organically and instinctively as the track played.

"It was a wild-pitch acid house mindset and meant there was a degree of uncontrolled rawness that complimented the ethos of the track perfectly.”
