Josh Sondock has directed an ingenious video for US singer-songwriter Nick Leng that dissembles the process of making a video - indeed the whole idea of image-creation - in one bravura continuous take.

It's a bit more complicated than that. Sondock's video for Leng's Morning/Midnight is a film with a Russian Doll structure - or perhaps reverse Russian Doll. Several performances of the track by Leng come together, layered on top of each other. We move outward from a performance that is revealed to be on a monitor, which is then part of a scene which includes Leng performing... and that is revealed to be a take, on a screen. We move out, and also back in, thorugh the increasing number of layers...

Sondock has described this as "a one-take music video in which a musician makes a one-take music video in which a musician makes a one-take music video in which a musician makes a one-take music video..." And so on. That is exactly what it is - but, conversely, that does not quite do it justice.

This has the rare quality of being a brilliant concept, which is quickly evident. But there is a uncharted end point, somewhere ahead, which keeps you hooked. Furthermore this idea has tremendous resonance - especially but not exclusively for filmmakers - meditating on the almost ludicrous ubiquity of screens in daily life.

Perhaps most crucially of all, this is all about a great (and quite complicated) idea, executed well, and with great clarity. An exercise in smart creativity that makes it one of the most satisfying watches of the year so far.
