Sufism is popular, particularly with young Moroccans. It's described as a mystical dimension of Islam and can be found in many Islamic groups, including Sunni and Shia groups.
Sufis are known for their tolerance, modernity and balance between religious obligations and secular pursuits such as music and art. Sufi gatherings combine chants, prayers and debates, giving followers an avenue to discuss issues ranging from faith and politics to environmental degradation, drugs and social charity.
The guys in the photo are Gnawa musicians from the Sahara. Apparently they are the descendents of Europeans and African slaves brought to Morocco between the 12th and 17th centuries.
Their music was low-pitched bluesy chanting of Sufi verses, carried by a booming drum beat, lots of hand clapping, jangly krakeb cymbals (they let me have a go - but only once) and some funky dance moves and dervish work.
The Gnawas are also known for their healing rituals, in which they treat anything from a plant disease to a scorpion sting with colours, scents, cultural imagery, animism and fright.
