Orgullo Fisura is a heavy punk band from Buenos Aires, Argentina, who fuse traditional heavy metal with punk aggression and socially charged lyrics rooted in underground resistance culture.

The band has been a consistent presence in the Buenos Aires underground scene, with a catalog that also includes earlier releases such as "HeavyPunk de carretera" (2017).

Pedo — the word is Spanish for 'fart,' and the name is entirely intentional — is a death/thrash metal and punk band from Neuquén, the capital of the Neuquén province in Patagonia, a city that has produced a surprisingly robust metal scene given its distance from the cultural centers of Buenos Aires and Córdoba. Formed in 2014 according to their current incarnation (with earlier activity noted on Metal Archives going back as far as 2007), the band plants themselves in the scatological, horror-inflected corner of extreme metal where bands treat shock value and black humor as legitimate artistic tools — a tradition running from the early grindcore scene through Brazilian death metal and into the Argentine underground. Their lyrical themes of feces, horror, and humor are not merely juvenile provocation but part of a coherent aesthetic that strips away any pretension from the genre, delivering death/thrash with a punk band's lack of concern for dignity or commercial palatability. Neuquén's metal scene has historically been tied to the broader Patagonian metal ecosystem — a region that developed its own distinct identity within Argentine metal, partly through isolation and partly through the influence of indigenous Mapuche cultural elements that some local bands have incorporated, though Pedo operate at the rawer, less ceremonial end of the spectrum. Their current on-hold status suggests the project has stalled without formally disbanding — a common state for underground bands in Argentina's interior, where life logistics and the difficulty of maintaining momentum in geographically isolated scenes often pause rather than end musical projects.
