I first heard this through cheap, black earphones. I was hiking in the mountains on Gran Canaria, Spain, 1,800 metres (6,000 feet) above sea level. I was scaling an outcrop at the centre of the island called Roque Nublo. It was formed by a volcanic eruption 4.5 million years ago. I never look at my photos of Roque Nublo any more. But I listen to this song.
