I was surprised too! I had not heard Amesouers, Batushka , Medico Peste and Nahash before, but I like what I hear and am happy to see the more recent trend of black metal cross-pollinating with post-metal, doom, punk, shoegaze, etc.
One of the things I find fascinating about metal is this development of different sounds from country to country. You're right to say that Norway came along very early, as did the South American scene with its more thrashy interpretation from bands like Sarcofago, Sextrash, Vulcano, Mystifier, etc. I hope that regional aspect isn't lost (or lost already) with the interconnectedness of the internet, but on the whole the internet has probably had a massively positive effect on music in general.
And your country had a small but interesting death metal scene too! I am fond of Conscious Rot, Regredior and Ghostorm and even have a few old demos from those bands.
