The offstage sequences can be revealing - in one scene, Jones recalls the abusive step-grandfather who inspired her aggressive musical persona- but director Sophie Fiennes sets such a languid pace that the songs can't come soon enough.

The non-chronological editing oddly makes Jones look as if she's everywhere at once, unbounded by the laws of time and space that ordinary mortals are subject to.

Fiennes provides a meandering observation of the woman behind the glamazon, disco diva and full-throated and furious singer/performance artist in this unstructured doc.

This is an elliptical, at times frustratingly formless, but always watchable and fascinating series of sketches of an artist who really isn't showing any sign of slowing down.
