Hm, this is a very interesting mix of overtone vocals with some energetic, rhythmic drums. Very nice!
On Ensemble is a group of four young taiko artists from North America. They combine traditional sounds with modern influences like jazz or electronic music. "Gengakki Ver 1.1" is a fine shamisen piece featuring great percussions (it starts very slow, don't be confused by that). They also have some videos on their site which are worth watching!
(thanks to hawa from they did it who sent me a bunch of links to shamisen/taiko music)
