His voice isn’t a pretty one; it’s rough, dry, and has only a limited range before it breaks. Neither is he a particularly talented singer; he’s off-pitch much of the time (and not in the desired quarter-tones of Arab music either), and changes between high and low notes are never smooth. Still, it’s an evocative sound; full of soul, and with a sparseness that perfectly matches the desert around us. The pale pink light at the horizon announces another day; he just finished his morning prayers. Now he’s singing verses from the Quran, while making tea on the camp fire that drives away the morning chill. This morning is the same as countless desert mornings experienced by his father before him, and his grandfather before that. His name is Salima, and he’s from a centuries-old line of Moorish goat herders. Sometimes he makes some extra money guiding tourists on his camels. That’s why we’re sharing breakfast in the middle of the Sahara desert this morning.
