It would probably make the analysis a bit difficult, but it would be interesting to see it incorporate more international bands.

Some bands are still going strong, although my favorite band Mago de Oz feels like it definitely peaked between 2000 and 2010 with the release of the Gaia albums. I'm not sure that I'd call all their albums power metal, but some of their newer stuff is definitely more power metal-y.

If anyone is looking for a great Spanish metal album, I'd recommend checking out Gaia II: La voz dormida. It tells a really ambitious story with amazing music to back it. And it ends with an epic 21 minute song that I don't even know how to describe.

Mago is Folk Metal. Also, before Gaia there was Finisterra which was everywhere.

"2000 and 2010 with the release of the Gaia albums"

That is when I was listening to them and did not follow on them later on. Did they produce anything interesting after that? Even just a single good song?

I don't think Mägo de Oz was power metal, but their early 2000s material definitely had some influences, since power metal was such an important current in European metal at the time.

Mägo de Oz has been active since 1989 and just released another album this year. Lèpoka is a more folky band that nevertheless sound very much MdO inspired. Still alive and kicking :)

Spain had Basque speed metal bands, but not Power. Also there's Reno Renardo but it's an obvious parody of Metal, a la Nanowar.

I can't tell from your comment whether you're saying that there were no power metal bands in the Basque Country, or more broadly in Spain... If it's the latter: there was absolutely a power metal scene in Spain. Avalanch, Warcry, Dark Moor (in the article) were power metal all the way and extremely prominent in the broader metal scene - they were some of the biggest metal bands of the early 2000s. Saratoga and Tierra Santa were not strictly power metal, but very closely adjacent (especially the latter, both lyrically and musically). There were plenty of smaller bands trying to make it in the space, too.

Yeah, I forgot about Warcry and Avalanch. Tierra Santa definitively had some overlap with Power Metal.

I was about to say 'Basque Power Metal' bands. Berri Txarrak it's more akin to Rise Against. Su Ta Gar it's speed metal with some thrash influences.

Big Nanowar fan here, but I would not day they parody metal...I mean, they obviously do but at the same time they actually like metal. So, it's not your typical parody, it's more kind of an inside joke.

The same with Reno Renardo, obviouly they do tons of references to the most known bands.
