This is the wonderful sound of the sea on the rocks which Algy heard while he was waiting for the tide to come in and wash his sandcastle away.
This is a birthday treat for Algy’s friends, but especially for those, like Kara telescopical, who have never heard the sea in reality. This recording scarcely begins to convey the wonder of it, but Algy hopes that one day you will hear the sea for yourselves 🙂
