"I was twenty-four years old, working as a member of a crew that was hired to deliver a sailboat. We were at sea for a total of twenty-two days. It was very boring. After the first three days, I had read every book I brought with me. There was nothing to do for entertainment except to watch the clouds and take naps. For days and days, there was no wind, so we simply puttered along at a few knots by running the engine while the sails luffed. I would lie on my back on the deck or on a bench in a cabin and stare out through the Plexiglas window. It was during these long days of complete inactivity that I had several musical hallucinations.
Two of the hallucinations began from monotonous and ever present sounds that were generated by the boat itself. These were the buzzing of the reefer(the small refrigerator), and the whistling sound of the rigging in the wind. Each of these sounds transformed into never ending instrumental solos. The transformation into music was such that the original sound and its source were forgotten, and I lay there in my lethargic state for long stretches of time just listening to what sounded like stunning and beautiful compositions."
