On the contrary, anything unscientific is great. I am a musician myself and I find proof based scientific discussions very claustrophobic at times.
All I am trying to say is, in this case, the article is a bunch of opinion from a Jazz musician about fellow Jazz musicians and bands. How does this fit in with other HN threads?
I would say that something like Frank Zappa on censorship [1] [2] is much more suited to HN discussion than this link.
