AI, Amplifiers, and Argentina: How Global Metal Headlines Echo Through South America's Underground
Every so often the global metal news cycle drops a headline that, almost by accident, plants a flag directly in South American soil. This week it happened when DEF LEPPARD guitarist Phil Collen sat down with Buenos Aires station Rock & Pop 95.9 FM to talk about artificial intelligence in music. It's a small detail in the grand scheme of a packed news week, but it's worth pausing on, because it says something about where our region sits in the global conversation — not on the sidelines, but increasingly part of the dialogue shaping where metal goes next.
AI and the Soul of Metal: Collen's Take Lands in Buenos Aires
Collen's comments were measured rather than alarmist. Asked about musicians using AI tools to generate melodies, harmonies, and lyrics, he offered a pragmatic take:
"I think you have to accept and embrace any new technology."
It's an easy line to quote and a much harder one to sit with if you've spent years grinding out riffs in a rehearsal space in Lima, São Paulo, or Santiago with secondhand gear and borrowed amps. The AI-in-music debate tends to get framed as a First World problem — session musicians worried about replacement, major labels chasing efficiency — but it has real implications for a region where the DIY ethic isn't a brand, it's a necessity. South American death, black, and thrash bands have built entire careers on scarcity: four-track demos, self-funded pressings, flyers photocopied at 2 a.m. If AI tools start flattening the barrier to entry for generic songwriting, the raw, unautomatable grit of bands coming out of this region's underground becomes even more valuable, not less. That's a conversation worth having at every local show, not just on Argentine FM radio.
VOIVOD's Video Game and the Region's Thrash and Prog Faithful
Elsewhere in the news, independent developer Chaosmonger Studio dropped a new demo trailer for "Voivod: The Nuclear Warrior," the officially licensed Metroidvania built around the Canadian legends' dystopian sci-fi universe. It's a reminder that VOIVOD's angular, concept-driven weirdness never really went out of fashion — it just moved into new mediums. For a region that has long embraced thrash metal's technical and conceptual extremes, this kind of crossover is relevant. South American thrash and crossover acts like Lascados and speed-thrash outfits such as Nuclear Trauma and Orgia Nuclear carry forward exactly the kind of riff-first, concept-friendly aggression that made bands like VOIVOD cult favorites in the first place. If a video game can reintroduce a new generation to VOIVOD's catalog, it's not a stretch to hope that same curiosity trickles down into discovering the region's own thrash lineage — a scene with 116 active thrash bands in our index and still criminally under-covered.
On the more technical, prog-adjacent end of things, bands like Eleven Strings and Arithmetic Overflow show that the appetite for conceptual, genre-blurring metal is alive and well south of the equator, even without a AAA game budget behind it.
Marty Friedman's New Album Tease and the Enduring Pull of Thrash Metal
Former MEGADETH guitarist Marty Friedman, never one to sit still, confirmed in a recent interview with VRP Rocks that he's already deep into writing for the follow-up to 2024's "Drama."
"I have been writing new music for the next album."
Friedman's restless creativity is a good excuse to talk about the health of thrash metal more broadly, a genre that refuses to die no matter how many trend cycles try to bury it. South America has always had a complicated, loving relationship with thrash — it's arguably the genre that broke the region onto the global metal map decades ago, and it remains one of the most populous tags in our index. Bands like EvilAlive, Dekapited, and Fullrage are proof that the formula — tight riffing, speed, and zero patience for filler — still resonates with new listeners discovering the genre through legacy acts like Friedman's former band. Speed metal purists haven't been left out either, with acts such as Démona and Defeater keeping the tempo dial pinned well past comfortable.
GN'R's 2027 Hiatus and What It Means for Touring Trends
Slash confirmed on "Trunk Nation" that GUNS N' ROSES will take 2027 off from the road to focus on new material, telling Eddie Trunk plainly:
"We have so much material."
It's a notable data point in a touring landscape that's been reshaping itself constantly since the pandemic. Major legacy acts pulling back from the road to write doesn't necessarily mean less activity overall — if anything, 2026 is shaping up to be a landmark year for metal bands touring globally, with mid-tier and underground acts filling calendar gaps left by the headliners resting between cycles. For South American promoters and fans, this is exactly the kind of year to watch regional routing closely; international acts recalibrating their schedules often means more flexibility for festival bookers here to slot in acts that might otherwise be squeezed out by overlapping stadium runs. Keep an eye on upcoming shows in your city — 2026 could be unusually active for South American stages precisely because some of the biggest global names are stepping back.
Sharon Osbourne, Megadeth, and the Weight of 80s Metal Legacy
Sharon Osbourne's recent confirmation that organizers "really, really wanted" MEGADETH for last year's "Back To The Beginning" farewell concert for Ozzy Osbourne and BLACK SABBATH is a small anecdote with big resonance. It underscores just how central 80s metal bands remain to the genre's sense of identity, even as the scene fractures into a hundred subgenres. That reverence for the foundational era isn't unique to the UK or US — it's deeply embedded in South America's own metal history, where Sabbath worship and NWOBHM influence shaped entire generations of heavy metal songwriting. Regional heavy metal acts like Odisséia, Trovão, and Massacration all carry that classic-metal DNA forward, proof that the best heavy metal songs of the genre's golden era still inform what gets written in rehearsal rooms from Córdoba to Curitiba.
Keeping the Regional Fire Lit: Death, Black, Stoner, and Beyond
None of this week's headlines originated in South America, which is itself a reminder of why building out coverage of our own scene matters. The region's death metal underground remains enormous and underdocumented — acts like Eternal Necrosys, Thanatofilia, and Hereticae represent a death and blackened-death lineage that deserves the same attention routinely lavished on European and North American scenes. The black metal side is just as deep, with atmospheric and melodic acts such as Insanity Storm, Introspectiva, and the blackened Brazilian force 7 Peles building catalogs that rival anything coming out of Scandinavia, minus the press coverage.
Stoner and doom, meanwhile, might be the most quietly thriving corner of the regional scene right now. Satanes continues to mine heavy, fuzzed-out doom/stoner territory, while post-metal and sludge act Inner-I shows the genre's bleaker, more atmospheric edges. With 59 stoner-tagged bands in our index and essentially zero dedicated coverage until now, it's a scene ripe for a proper spotlight — one we intend to give it.
The throughline across all of this week's news — AI anxieties, legacy band farewells, touring pullbacks, new game adaptations of old sci-fi concept albums — is that metal as a global culture is constantly renegotiating its relationship with technology, nostalgia, and endurance. South America's scene has been having that same negotiation for forty years, just without the same spotlight. If you're in a death, black, heavy, thrash, or stoner band grinding it out in this region and you think your story belongs in that conversation, submit your band — this index exists specifically to make sure the next headline about the best metal bands in the world doesn't forget to look south.
