As part of my video business I worked on a project for the 2005 New York Shakuhachi Festival and have since been associated with a really fine Shakuhachi teacher Ronnie Seldin in NY
If interested, you can buy the DVDs and other items at this site. http://www.nyogetsu.com/
I love the shakuhachi and wish I had the time to learn more about it. The history, when the only people permitted to play it were ronin samurai who became priests, is very closely intertwined with our martial arts.
