Light falls on Chefchaouen, scattering a palette of blues. This hilly town in Northern Morocco is known for its indigos and robin's-egg blue doors and windowsills, making the sky feel closer to earth. Somewhere inside a group of women gather, dressed in beautiful embroidered robes. The room is filled with anticipation of the hadra, spiritual ceremony which is about to begin. Ms. Rahuoum El-Bekkali nods to her accompanist, who plays the Bendir drum. The women's choir begins to sing.
