My posting a list of Blues artists from outside of the USA should in no way be taken as a diss on USA Blues artists. Frankly, I was blown away by how widespread the Blues is throughout the world. Here's the geographical list of nations* that I culled from those L through P named artists alone [I'm sure there's more nations mentioned on theblueshighway.com A-K pages]

I'm combining all the artists mentioned in England, but citing Ireland and UK separate from that. Sorry if that's politically incorrect. I'm aware that there are differences between England and the UK and parts of Ireland and the UK, but I confess that I'm challenged to know when to use one reference or the other.

I'm also combining all the references to Canadian provinces into one citation of Canada.

Also, I think that Scandinavia includes countries like Sweden and Denmark, but since I'm not sure about that, I'm going to give separate listing to those nations that I think are in Scandinavia. [I could blame US public schools for this lack of geographical knowledge, but I won't. After all, in this Internet age, anybody with Internet access can find any information that she or he wants. I'll admit I haven't looked up this information yet. Perhaps someone can correct my uncertainty about what constitutes Scandinavia. If not, I'll check out Google later on.
So, that said, here's the list that makes me say Wow! I guess the Blues really has a presence outside of the USA. I'm not sure how it's received in these places, but it sure is there.

I don't see any African, Caribbean, Middle Eastern, or Pacific Island nations listed. {I'm counting Turkey as a European nation, though I suppose it could be counted as Middle Eastern?}

And there's only one Latin/South American nation in that blues highway list.

I'd be very surprised if many nations in those geographical areas weren't represented by A-K Blues artists.
