I have only been playing Flamenco for a about a year at the time of this review... I absolutely love it! I am fortunate enough to have a great teacher locally to help guide me twice a month. I am also happy to have found Kai and his “Flamenco Explained" to fill in an supplement areas of technique / theory / history / etc... that an hour long lesson is limited by. With all of the videos and information here I am free at my will to explore an grow further with easy access especially if you have the iPhone app. Definitely happy to have Kai’s wealth of knowledge an passion for this beautiful music at my finger tips.
