Devil Master's G.I.S.M. Cover Reminds Philly That Hardcore Never Left Black Metal's DNA

There's a reason Philadelphia keeps producing bands that refuse to sit still inside a single genre tag, and this week that reason has a name: Devil Master. The blackened hardcore outfit just dropped their cover of Japanese hardcore legends G.I.S.M.'s "Death Anthem," and if you needed a reminder of why this band matters to the Pennsylvania metal scene, this is it. The track arrives ahead of their new record 'Bloody Dreams,' due September 4 via Relapse Records, and it's exactly the kind of gesture that tells you a band knows its lineage cold.

G.I.S.M. occupies a mythic space in extreme music history — the kind of band whose influence outstrips their discography, whose sound bled from hardcore punk into something darker and more theatrical decades before "blackened crust" was a genre tag anyone used. For Devil Master to reach back across the Pacific and forty-plus years to pull that thread forward says something about where Philly's underground sees itself: not as a regional curiosity, but as a continuation of a global conversation about how ugly, ritualistic, and cathartic heavy music can get. This band has spent years fusing raw black metal, deathrock theatrics, and hardcore's street-level aggression into something that sounds like nothing else coming out of the city right now, and "Death Anthem" is a flex disguised as a tribute.

It's also a good moment to point out that Devil Master's whole approach — genre-agnostic, historically literate, unwilling to be boxed in — is basically a blueprint for what makes the Pennsylvania metal scene worth paying attention to in the first place. This state doesn't have one signature sound. It has pockets: Philly's crust-and-black-metal underground, Pittsburgh's death metal lifers, Lehigh Valley's metalcore machine, and a scattering of doom, thrash, and speed metal acts holding it down in between. Devil Master sits at the crossroads of several of those pockets at once, and 'Bloody Dreams' looks like it's going to be a statement record for the whole regional underground when it lands next month.

Grindcore's Basement Gospel Turns 25

Speaking of records that reshaped extreme music from unglamorous surroundings — this week marks 25 years since Pig Destroyer tracked what became a grindcore cornerstone in a basement, 32 minutes of blast-beat brutality that still gets cited as a genre-defining achievement a quarter-century later. It's worth using that anniversary as an excuse to talk about grind and its uglier, slower cousin, slam death metal, because Pennsylvania has quietly built up a real bench of bands working in that pocket even if the wider metal press hasn't caught up yet.

Slam and technical death metal acts across the state have been grinding away (pun intended) in DIY basements not unlike the one that produced that landmark record — the same spirit of low-budget, high-impact brutality that doesn't need a major label rollout to hit hard. If you're digging into the deeper cuts of the Pennsylvania metal scene right now, this is the corner worth exploring: unglamorous, uncompromising, and largely self-sustaining, exactly the way grindcore's founders would have wanted it.

Mercyful Fate's Return Puts Traditional Metal Back in the Conversation

Mercyful Fate announcing their first live show since 2024 — so far just a single festival appearance — is a reminder that the NWOTHM revival isn't slowing down, and Pennsylvania has skin in that game too. King Diamond's theatrical, occult-soaked brand of heavy metal helped define an entire aesthetic that traditional metal bands are still mining decades later, and that includes homegrown acts working the same vein of classic riffing and dramatic songcraft.

Philadelphia's own Assassin has been carrying that torch locally, part of a small but dedicated NWOTHM and heavy metal contingent in this state that deserves more ink than it typically gets. When a band like Mercyful Fate — genuine genre architects — announces even a single show, it sends a ripple through every band drawing from that well, reminding audiences that this style of metal isn't nostalgia, it's a living tradition. Keep an eye on upcoming shows around the region; traditional heavy metal nights have been popping up more frequently in Pennsylvania clubs, and that's not an accident.

Hardcore's Festival Circuit Keeps Growing — And Philly Should Be Paying Attention

The first wave of bookings for the 2026 'For The Children' festival dropped this week, and it's a stacked hardcore bill: Death Threat, Cro-Mags, Seahaven, Fatal Realm, Inclination, Laid 2 Rest, One Step Closer, and plenty more. This is exactly the kind of lineup that should have Pennsylvania hardcore kids circling dates, because the through-line between festivals like this and what's happening in Philly, Allentown, and Pittsburgh basements is direct and unbroken.

Devil Master again deserves a mention here, since their entire sonic identity is built on the bones of hardcore even as it mutates into something blacker and weirder. The band exists as living proof that Pennsylvania's hardcore scene and its extreme metal scene aren't separate ecosystems — they're the same water table, just tapped from different wells. Anyone booking local hardcore-adjacent bills in 2026 would do well to study how festivals like 'For The Children' are curating across subgenre lines rather than sticking to a single lane.

Riot Fest's Scheduling Chaos and What It Means for Touring Bands

Elsewhere on the festival circuit, the 2026 Riot Fest daily schedules are already generating debate, with Tool going head-to-head against Nas, and a three-way scheduling collision between Insane Clown Posse, Pierce The Veil, and Elvis Costello forcing fans into some genuinely absurd choices. It's not a Pennsylvania story directly, but it's a useful data point for anyone tracking how festival booking logic works in 2026 — genre lines are dissolving on these bills, with metal, hip-hop, pop-punk, and legacy rock artists sharing real estate in ways that would have seemed unthinkable a decade ago.

That same blending is happening at the club level here at home. It's part of why a band like Autumn Kings can bring in former Killswitch Engage vocalist Howard Jones for a guest spot on a new rap-rock leaning track, "Young Bloods," off their forthcoming album 'Epiphanies,' and have it feel like a natural evolution rather than a gimmick. Genre purism is having a rough decade, and honestly, the Pennsylvania scene — with its long history of hardcore, metalcore, and thrash cross-pollination — is well positioned to benefit from that shift rather than resist it.

New Music, New Faces, and the Shape of 2026

A few other national headlines are worth filing away as signs of where things are heading. Wayfarer's return with "Perdition's Crossing," featuring 16 Horsepower's David Eugene Edwards, continues the blackened Americana lane that's found real traction with metal audiences who want atmosphere alongside aggression — a sound that shares some emotional DNA with Pennsylvania's own doom and post-metal acts working in slower, more atmospheric territory. Shining's continued avant-metal explorations and Darko's new EP featuring members of Northlane and Molotov Solution both point toward a 2026 where hybridization, not purity, defines what gets called "new metal bands 2026" worth watching.

Locally, that hybrid instinct is already baked into how Pennsylvania bands operate. Whether it's the atmospheric weight of a post-metal act working slow-burn dynamics, the technical sprawl of a progressive death metal band, or a black metal project pulling from folk and doom textures, the state's underground has never been shy about genre-blending. If your band is doing something in that spirit — traditional heavy metal, post-metal, speed metal, slam, or anything that doesn't fit neatly in a box — submit your band and get it on our radar.

Keep Watching Philly's Underground

With 'Bloody Dreams' landing September 4, Devil Master is about to have a moment, and it's a well-earned one. The band's willingness to reach back to hardcore's international roots while pushing forward into blackened, ritualistic territory is a masterclass in how a regional band builds a global reputation without losing its local edge. Pair that with the ongoing NWOTHM revival energizing acts like Assassin, the deep grind and slam death metal bench quietly building in basements across the state, and a hardcore festival circuit that keeps proving Pennsylvania bands belong on national bills, and you've got a scene that's busier and more interesting heading into 2026 than it's gotten credit for. Check upcoming shows and catch these bands while the rooms are still small enough to feel the floor move.
