A real sunset on a sandy beach at Khao Lak, Thailand: waves rolling in as the light goes, then the same evening's waves through the night. Twelve hours for sleep.
The sound was recorded on 18 October 2026 by an iPhone on a tripod at the left end of the beach, from about ten to six in the evening. Nobody speaks.
The first thirty-four minutes are the sunset as it sounded. One distant boat was replaced with waves from the same evening, and a steady engine hum was turned down.
After that, an eighteen-minute stretch of the same evening's waves repeats to the twelve-hour mark, joined with soft crossfades. Distant boats are removed, the crickets are left out and the highs are softened for sleep.
