All the people that complain about the DJ, it was not his fault. It was the sound board engineer. The music from the DJ drowned the Shamisen music. If his brother was there for that song it would have been a little louder with the two playing but the techno should not have overtaken the Shamisen sound level. Other than that it was pretty awesome.
This brother is my favorite, he has much more amazing skills, I was at both shows. Both are great, but he is better, cuter too, haha. If you want proof of his better skills, they are right here in this video.
