Ju-ken information 
It’s so nice to see someone keeping up with this man. I put up a short clip of him and Hotei on youtube under another username…shinyaslove. They used it during his appearance at Fender under his bio which shocked and pleased me no end. I noticed that you don’t have Heath’s “Mind” listed. He was in that pv and enjoying himself immensely. I signed up to follow your blog if you don’t mind.
Thank you! I remember seeing that clip for Fender; that’s great that it was your video.
This “Mind”? I wasn’t sure if it was a PV or a TV performance, so I didn’t add it. One of the things I like about him is that he does seem to enjoy his work.
Followers are good! I don’t make new posts all that often, though; mostly I just update the yearly post (last update: a brief soundcheck from the March performance with Mitsuhisa Sakamoto and his report with pictures).
