On a warm breezy walk in the Essex countryside, we left the microphones in a tree at the top of a rarely used bridleway to record the sound of the wind. The tree was one of an outcrop that lines fields of barley and home to a robin. High above the fields are skylarks, not a common sound these days. In the distance there's the odd ice cream van too in the Lea Valley Park. It's a lovely spot to get away from everything and soak up the warm sun grassy freshness and summery sounds. Recorded in June as London's first lockdown started to ease.
