The Flaming Lips have released the supremely Not Safe For Work trailer for the band’s concert film Freak Night.

The documentary highlights a free performance from the band at their native Oklahoma City’s Zoo Amphitheatre from last October. Billed as "the largest costume party in the Midwest", you can see the crowd does justice to that lofty title.

You can watch the whole documentary next week for free on the Flaming Lips' official website.
