The most successful modern prog music nation?

I think looking at any kind of ratings, rankings, end-of-the-year lists or most expected albums lists, Norway would surprisingly or not, come up as the most prominent and consistent nation nowadays in terms of quantity and quality of releases, whether it be their predominant interest in exploring and expanding the possibilities of 70s influenced symphonic prog, with strong leanings towards bands like Genesis, Yes, Crimson, ELP, Cathedral, mixed with their own sensibility and traditions in folk music, or through their menacing and forward-thinking progressive metal and metal-adjacent albums, always very quirky, yet dark, occasionally jazzy and funky... But the condition that Norway is the present-day prog rock superpower is quite strong, this is my observation!

No doubt that the UK is not letting go and is perhaps on par with (or often even surpassing) their Scandinavian "rivals" when it comes to originality and merging prog rock's mentality with the prevalent sounds of the modern age, the mainstream, if you will, resulting in an interesting injection, at least personally for me, of a very intriguing pop sensibility for what concerns British prog rock releases of the recent years.

In any case, prog rock is in an interesting state of being, and it is by all means evolving, whether or not everyone notices. Evidenced by the emergence of a myriad of new bands that seem to be allocated to this category, when in reality, such bands are quite fluid and even genre-less, and above all, performing quite well commercially, receiving lots of attention, which ultimately leads to the appearance (or rather, re-appearance) of the term/word/genre of "progressive rock" and "progressive music", when put more generally.

Coming back to the original discussion, the US is as usual very prominent, although I am finding it a bit more difficult to be as intrigued by most American prog releases, as I am by their European counterparts. Naturally, Sweden, Italy, Germany, the Netherlands also have their very strong and influential representatives in the prog scene. And then comes the question of the revival of legacy bands, which seem to be touring so often nowadays, with completely new lineups, always busy releasing new music... But this, I guess, is a completely different conversation. These are my thoughts on this thread!

I guess, things may look rather differently when we talk about strictly defined Progressive Rock instead of progressive music.

Osibisa is great. A Multinational line-up. 

Not necessarily related to the moshkito posting you referred to (and not necessarily is disagreement with you), but I think relevant differences between nations exist regarding (a) the emphasis on arts/music in education and (b) the system of social support, taxes etc., namely how viable it is to exist on something like a half time job (or no job at all) if you put much time into music without it paying for the bills. Significant differences exist between wealthy nations in these respects.

They count because they are a great band. 

And especially, if they sing in English. 

Couldn't resist! 

Good prog is where we find it.  I rather enjoy the Mongolian group The HU!  Perhaps not prog in the classic sense, but very aggressive and creative.  

As far as most successful nation....measured by tax receipts?  Touring?  Product releases?
