UPDATE: There's a new teaser called "Switch Seeks Same" featuring music and seriously strange visuals.
The updated website features a flickering looped video showing a figure (seemingly) unconscious on a table - it's pretty creepy. Check it out. One fan revealed on Instagram that calling the hotline leads to "some sort of voice mail thing. It sounded like a serial killer making threats while someone was vacuuming gravel behind them."
Andersson (also one half of The Knife) hasn't done much under the Fever Ray banner in a few years - her only Fever Ray record came out in 2009 - so this is a rare shaft of light into a particularly mysterious world.
Check out the new pic and vid below.
