A relaxed mountain walk. Dancing through the mountains. Warming Up in Lower Regions - Reaching Upper Regions - Enjoy the View. So this is a mountain hike as imagined by a machine, because "Alexis", an invention of author Horst Grabosch, is supposed to be a machine. Yes, it is conceivable that an artificial intelligence would produce such dance titles, but we still hear a few twists that foreshadow human creativity. Besides, we doubt that a machine could create such a relaxed, happy mood. But we're happy to be taught better, and after all, we don't care who we can thank for this musical fun.
