Tied to a railing, the Lento box records alone. It's about two in the morning along the river bank east of Burnham-on-Crouch in Essex. Wind is blowing inland from the east, light, gusting to moderate. Sky dark, and heavy with cloud. Huge rainclouds are approaching, currently located out over the North Sea. When they arrive this whole area will be subjected to long periods of persistent, often squally rain, lasting well into the next day.

For now though the Lento box is dry. Its microphones capturing just the sound of the incoming tide as it steadily advances up the seawall. Angled directly towards Wallasea Island, the expanse of estuary water between the seawall and the opposite bank of the River Crouch can be heard as a wide and spatial backdrop.

Throughout this 30 minute passage of nocturnal time, the way the water plays along the seawall constantly develops and evolves. Sometimes individual waves form into resonant airpockets, producing fleetingly melodic notes. Wave energies surge and dissipate, surge and dissipate, edging closer and closer to the microphones on the rising tide. What's consistent is the timbre of the water as it washes over the rippled ridges of the seawall. To us silvery. Each individual wave captured in sharp spatial detail that you can experience in full using headphones or AirPods.

At twenty three minutes an aircraft approaches from the east and passes over Wallasea Island. From left to right of scene. Reveals across the empty void of the sky how human activity can still be heard over this otherwise wild and empty landscape.
