Youngmin Lee, one of our tour organizers, saw my blog post of November 18th and let me know the Bogaji artist was Dukjoo Choi. There is a wonderful video of her show which took place a few years ago in Vienna. There is an English translation that explains the history of Bogaji also called Pojagi previously. You will notice the Austrians spell it Bozagi. https://www.youtube.com/watch?v=_2cZFt9gdqQ
