Asia Minor, other like this ?

Ragnarok from 1976, I'd say. I actually prefer Ragnarok. 

If you liked the flute a lot, then maybe To The Highe$t Bidder from Supersister, as well.
Sheshet from Israel is similar, maybe try out their one album. 

I love peaceful albums, so if you're looking for a relaxing ride, then try Nelson Angelo E Joyce (though that's MPB, a very different genre coming from Brazil)

I think you might like Rousseau's first two albums, A Flower in Asphalt and Retreat

Asia Minor is really one of a kind.  There are a lot of Camel influences but I assume you know Camel.  You might find more recent albums by Bahraini group Osiris to have similarities.  I'll think more about it and post if anyone else comes to mind.

Try Harmonium's Second Album "Si on avait besoin d'une cinquième saison"

Hey, thz very much for your help. I've discovered some interesting artists.

Have you tried Sanhedrin's Ever After? It's one of those records that have been on my wishlist for years and for some reason I haven't bought yet. I gave it another listen on Youtube a couple weeks ago and it sounds like something that could interest you.
On the flute front, but with a very different sound, I can't help but recommend Gotic's Escenes. It's more on the symph/jazzy side of prog with folk touches, with melodies to die for (check for instance Historia d'una gota d'aigua)
