For Melaya Leff:
Check out Faten Salama's website. At the bottom she has an instructional DVD for Melaya Leff. Below is the description:
"Melaya: If you have been waiting for a Melaya Leff teaching tape, with not only choreography but information regarding costuming, rationale, motivation, styling, expression, interpretation and appropriate cultural context, this is the DVD for you! "
You can also listen to an excerpt. It is at the bottom middle of her webpage.
