Nice - I’m no expert, but are you sure that isn’t a soprano sax rather than a clarinet?
These examples of polysaxophony are intriguing, but I wouldn’t want to derail the thread - so with that in mind I started a separate one on impressive examples of of musicians playing two instruments at the same time.
It would be great if you and @Paintcharge could repost your examples there - I don’t want to steal your thunder.
