I bought one of Kirill’s pieces a little over a year ago. One of the 3D printed ones. It plays very well. I don’t play it much because I don’t like the feel of it in my mouth, same with the SYOS piece I bought (which doesn’t play nearly as well).
Regarding the controversy about the guy, there are two kinds of *******s in the world - those that know what they are doing and those that don’t. We have been dealing with a member here on the site lately that falls in the 2nd category; Kirill is one of the 1st kind. Hopefully he loses some of his ******* qualities as time goes on. I’ve been aware of him for many years, there are some you-tube videos from several years ago of him playing tenor and organ as a young teenager that are frankly quite stunning.
History is rife with a*h** musicians. My wife refuses to listen to Miles Davis. Me, I just accept the fact that they are broken or wounded in some way, as most of us are, and enjoy the music.
