This morning, we brought you news that Florence and the Machine's impending new album release was coming soon - but even we didn't think that we'd be hearing something this soon.

The star hosted a playback of her third album in full last night in London, and has just posted a new teaser video online, dubbed, 'How Big, How Blue, How Beautiful.'

The amazing-looking video sees Flo doing some Sia-style interpretive dancing with a doppelgänger in an amphitheater in the middle of a jungle - as you do - over a brass-laden track.

It's not yet known whether 'How Big, How Blue, How Beautiful' is the title of the album, a song from the album or just the title of the teaser. It's all very mysterious, but the teaser can be seen below.

You can see some screenshots from it below.
