Oriental Dancer has a short piece by Morocco on Guedra - it's not a dance you're likely to learn from a teacher who wants you to 'shake it like Shakira' and, like most folk dances, it's intended as either ritual or for participation (i.e. not for audiences). The other problem with its accessibility for most belly dancers in the West is that it's not Arabic or Middle Eastern (Morocco, of course, is in North Africa) so the music and the style often doesn't 'fit' naturally into a term on, say, Oriental fantasy.
