You guys crack me up... sorry, but a guy wearing a mask, playing sorabji on the piano is not how one gets views.
Now if he posted a 30 second clip of playing sorabji with a cat singing along it might be a different story.
Even if that is his intention, who cares? not going to impact you in anyway. Just comment on the music or don't. Move on in life. It's still a good performance.
ps... if he wanted to increase his view count, you can buy 5000 views for like 10$. There are much easier ways to go about this then Sorabji. Focus on the music...maybe he doesn't speak english well and doesn't like to comment. Who knows and who cares.
