Totally Trippy Bird Songs

What happens when a musician records singers making sounds and then speeds them up to mimic bird song? Marcus Coates, a UK artist, and Geoff Sample, author, musician and nature recordist, teamed up for the past 3 years to produce the amazing "Dawn Chorus". It's a combination of bird sounds and video footage of humans imitating the sounds. You can read about it here
and see a video clip here. It's really something you have to see to believe.

Here's some more info:

"During rigorous fieldwork 14 microphones were placed around woodland to record birds during one morning of birdsong in Northumberland. This study is the first, simultaneous, multi-microphone recording of individual birds during the dawn chorus. From this multi-track recording each song was slowed down up to 16 times, then each human participant was filmed mimicking this slowed down song. Finally the resulting video footage was then sped up, returning the bird mimicry into its 'real' register. The speeding up of the film not only magically translates the human voice into bird song, but also emphasises unconscious gestures that appear uncannily similar to the physical behaviour of specific birds; a grandfather becomes a pheasant and teachers in a staffroom transform into chiffchaffs, robins and blue tits."
