One gets the sense that Björk isn't really making videos anymore, but seeking to create complete worlds. "Notget" is exactly that, taking place in something like a more artistic/alt Pandora, with Björk in distinctive masks and make-up.
"Leave A Trace" feels like a smoky/sultry/steamy photo shoot turned into a music video, which makes sense since it's directred by London photo/film duo Warren Du Preez and Nick Thornton Jones, who are masters at exactly that.
