It was, from a bridleway in rural Essex, the long slanted beam that first attracted us over for a better look. A fallen tree, perpendicular to the rest, lying half in and half out of a patch of woodland. We'd been trudging over claggy footpaths for an hour and it was coming on to rain. We needed to stop moving, and properly take in the landscape. The beam formed a natural bench, and something to climb on. After our ears had adjusted, we realised much of the human noise in the landscape was gone. The M25 to the south, and a road called the Crooked Mile which separates the edge of the Lee Valley Park and open country, had both sunk below the horizon. This spot was an oasis for listening. A place to enjoy the early spring sound of the local wildlife, and the rising and falling of the wind in the trees. Leaving the microphones behind on the tree trunk to record for a while, we went back to the bridleway, just to see where it went.
