OK... so this is a growing pet peeve of mine... labeling something based on the country that it hails from.
Ever since a scene developed in Sweden, around Melodic Death Metal, people have taken to using the band's origin as a descriptor. In the case of Sweden, it made sense, as that sound, at that time, was unique to that geography. However, it is not typically the case that the origin of the music actually impacts the music in a substantial way. Case in point, this band... is there anything "Peruvian" about their sound? I mean, if these guys were from Italy, would anyone have queued this song up and thought to themselves, "Hmmm... this sounds Peruvian."
Fire breath... not at all intended as a shot at you, as many people do this now. As I said, it's just a pet peeve. /rantover
