Query: fascinating mixture of styles

Here you have a real Gnawa band (Gnawa is an ancient Moroccan form of healing trance music), playing authentic Gnawa instruments, when after a while you realize you're hearing contemplative jazz piano parts. Then sax parts. This album showcases a very effective, subtle mixture of very different styles of music. The mix works, in no small part due to the sensitive treatment given the jazz instrumental parts. In less skilled hands, this would have all come off sounding clumsy and forced.....Here, the effect is fascinating and exotic.Also highly recommended is the other release by Nass Marrakech.
