The National Trust in Britain has teamed up with Jarvis Cocker, best known as the former front man for the band Pulp, to create an album comprised solely of natural sounds taking the listener on an audio journey around Britain.
The album is available for free on their website and well worth listening to. It moves freely, one track to the next, as the listener "walks" along a gravel path (crunch, crunch, crunch), listens to birds, hears waves lapping up on the edge of a pond, and then moves to the interior of an old manor. You hear an old fashioned music box, clocks ticking and chiming, and (my favorite) the incoherent chatter of children in a school room.
It's both soothing and evocative. Very cool to play for your kids!
