Jose Martinez Caro is an excellent teacher and I like his approach. You can contact him by sending him a message on utube. A few years ago he sent me a list of what he had available to sell. I think he has several DVD's. I forget the cost, but remember they were reasonable even with the euro conversion. He is in Spain. No idea what he has now. I concentrate on a different style, but got a lot of ideas from his utube videos. He uses what I call a mixture of the gypsy approach and the more structured classical approach. Payo Humberto is a good example of the traditional gypsy approach. Several others use the modern classical music theory approach. I prefer the gypsy approach because you tend to learn compas without thinking or counting it. This is a slower approach, but the final result is compas coming automatically, more emotion and ability to improvise.
Jose Tanaka has some great 1970's flamenco lessons you can get online, also some short videos on utube. I like Jose even though he teaches a lot of modern stuff. He can send you just traditional if you request. Interesting guy, American Japanese raised in a flamenco family. His teaching techniques are very good.
http://josetanaka.com/Adam del Monte and Jason McGuire are both excellent teachers, but focus more on the modern. Both are very knowledgeable in the traditional, but not sure what they offer for traditional instruction. They focus more on the classical music theory approach and compas taught with metronomes. The mechanical approach I will call it opposed to the emotional approach. For people not raised around flamenco sometimes it takes using both approaches.
