My wife and I went to the The Portland Taiko Ensemble tonight at the Kennedy Center in D.C. Cool concert. My wife said it was pretty authentic but they added some improvisation, largely because the group was made up of Japanese-Americans, one hafu woman, and a white guy. I have seen Taiko before in Japan and in America, but to me, they were the most entertaining. I am always impressed with the coordination and actually physical endurance involved. If you ever have a chance to see Taiko performed, especially the Portland Taiko Ensemble, I would highly recommend it.
