A city at low tide (sleep safe)
It is said that cities never sleep, but from inside north east London's Abney Park nature reserve, the silken hum tells a different story. It's the early hours of Christmas Day 2020. The park has long since closed. Nothing is about. From part way up the trunk of one of the many ivy-clad trees, the microphones are recording. Capturing the murmurations of the city at night. The traffic has retreated. The torrents of noise have shallowed. An urban sprawl that's gone out to the horizon. This is the sound of the city at low tide. The indeterminable rumble has thinned, to a soft hum. A panoramic hum that shifts, and billows, like curtains of audible silk. It's sometimes lost amongst the hiss and rustle of the ivy. A fox barks. An undulating tone fades in and out. Somewhere off, an unsteady bough squeaks, like a rusty garden gate. Lone cars pass in long hushing waves. Near to the microphones ivy leaves rustle. Then, is that something singing from through the leaf bare trees? Is it a silvery glimpse of dawn? It is a robin. But it's only dreaming. Dreaming out loud, of tomorrow's song.
