Águila Guerrera is a power and heavy metal band from San Miguel de Tucumán, Argentina, formed in 2017 by a lineup that includes Fran on vocals and guitar, Matías and Lomu on guitars, Ale on bass, and Massi on drums. The band contributed to the regional compilation Heavy Metal Desde el Tucumán Volume 2 and performed at the Tucumán Metal Fest 2021, cementing their place in the province's metal community. They have also shared stages with touring national acts as part of the northern Argentine heavy metal circuit.

Ícaro is a heavy metal band from Burzaco, Buenos Aires, Argentina, active since the early 2000s and listed on Metal Archives with a history stretching back to regional compilation appearances including Hermandad Metálica Vol. 2 (2000) and a Barón Rojo tribute in 2006. The band released their self-titled full-length album Heavy Metal in October 2013 through Metal Command Records.

Óxido came out of Elortondo, a small agricultural town in the Santa Fe province of Argentina, and embodied the spirit of what happens when heavy metal and punk collide in places far from the capital's scene infrastructure. Formed in 2014, the band operated in the lineage of Argentina's long tradition of metal-punk crossover — a tradition rooted in the 1980s when the distinctions between heavy rock, hard punk, and nascent metal were blurred in the hands of working-class musicians throughout the country's interior. Elortondo itself has a surprisingly deep metal history for a town of its size: the local heavy and punk communities organized themselves as far back as the 1990s under the banner of the 'Agrupación Heavy Punk,' a collective known as 'Brigadas Metálicas del oeste de Elortondo,' fostering a culture of underground music that persisted across generations. Óxido emerged from this lineage, mixing the rhythmic belligerence of punk with the riff-driven directness of classic heavy metal. Bands like Motörhead, the Brazilian pioneers of the metal-punk crossover, and the rawest strains of Argentine rock duro all factor into understanding their sound. Elortondo's isolation from the Buenos Aires scene forced a DIY ethic that can be heard in the raw, unpolished energy characteristic of interior province metal bands who never had access to major studios or industry contacts. The band split up before fully developing a documented catalog, but their presence reflects the vitality of Argentina's provincial underground, where metal survives on passion alone.
