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.
