I expect that this will be all over the place in the wake of Jarvis Cocker’s show from Port Eliot at the weekend. If it isn’t, it ought to be.

Coates, with specialist wildlife sound recordist Geoff Sample, recorded birdsong, slowed it down by a factor of twenty and then had his subjects sing the bird’s call, and accelerated the results back up to birdsong speed. Most compelling. Good with headphones.

(Also, how can this possibly not be related to anything else here, as the preview is presently advising me?)
