MG-15 were one of the earliest and most extreme hardcore punk bands to come out of southern Spain. They formed around 1982 in Nerja, near Málaga, at a time when Spanish punk was still raw, scattered, and mostly undocumented. What made MG-15 stand out immediately was how early they embraced a Discharge-influenced D-beat sound. In fact, they’re often cited as one of the first bands in Spain to fully push that style, which later fed directly into crust punk and heavier forms of hardcore.
Musically, MG-15 were loud, primitive, and aggressive from the start. Their early material was pure D-beat hardcore: fast, noisy, and unapologetically ugly in the best possible way. As the years went on, their sound evolved and picked up darker tones and metal influences, especially by the late 80s and early 90s, drifting into crossover and thrash territory without ever losing their punk backbone. Lyrically and visually, they leaned into bleak, confrontational themes that fit perfectly with the global hardcore underground of the time.
Before MG-15 existed, some of the members played in a punk band called Slips Y Sperma, which already hinted at the abrasive direction they’d later take. The name MG-15 itself comes from “Mortal Gas XV,” a reference to a deadly chemical weapon, which pretty much sums up the band’s obsession with destruction, chaos, and grim imagery. Nothing about MG-15 was meant to be pretty or commercial.
Their earliest recordings, like the 1983 demo often referred to as 'Caos Final', are now considered landmarks of Spanish hardcore for how raw and unfiltered they were. In 1984 they released the 7” 'Derecho a la Vida' on the Italian label Attack Punk Records, a release that helped spread their name beyond Spain and into the wider European punk underground. That record, in particular, is frequently mentioned as one of the first Spanish releases to really sound like Discharge rather than just being influenced by punk in a broader sense.
Later releases showed how much the band was changing and experimenting. 'Holy Earth', released in 1987, leaned into a darker and heavier sound, while the 1994 LP 'Clon' pushed further into crossover and thrash metal. Even so, MG-15 never fully disappeared; they resurfaced in different forms over the years, and in 2015 a compilation called 'Los Singles 1983–2005' pulled together material from across their long, uneven history.
MG-15 also appeared on the influential 'Spanish HC' compilation tape in 1984, which helped introduce them to international listeners and cemented their place in hardcore history. Over time, they earned a reputation outside Spain as well, especially among collectors and fans of early D-beat and crust. Today, MG-15 are remembered less as a polished band and more as true pioneers -one of those groups that showed how extreme punk in Spain could get, long before there was any real infrastructure or scene to support it.
