From local sludge heroes to international titans of metal, the Bosphorus Open Air Metal Festival cemented Istanbul’s status as a global capital for heavy music. For two days, the city pulsed with the sound of distortion, double bass drums, and the collective roar of thousands of fans.

In a city where the call to prayer echoes across historic streets, another call rang out this weekend—one of blast beats, guttural screams, and cathartic release. The Bosphorus Open Air Metal Festival wasn’t just a concert; it was a pilgrimage. Fans from every corner of the globe descended on Istanbul, turning the city into a black-clad sea of headbangers, ready for two days of sonic warfare and community.

Day One: Forging the Inferno

The first day began with local sludge metallers Kaptan Kadavra, whose socially conscious lyrics about real-world problems turned their crushing riffs into a rallying cry. Their performance was more than music—it was a statement, a call for awareness. The crowd responded instantly, moshing and chanting along.

Next came Alkera, Türkiye’s progressive metal pride, blending technical precision with emotional force. Their unique sound and stage presence gave the early crowd a jolt of energy that set the tone for the day.

Slovakia’s Doomas then cast a shadow over the venue, wrapping the audience in their melodic doom/death metal explorations of death, fear, despair, and pain. Their haunting melodies and relentless heaviness struck a balance between beauty and brutality.

Then came Türkiye’s own sludge institution, Black Tooth, veterans of the scene since the mid-90s, who channelled NOLA-inspired riffs and southern grooves. Their set was a whirlwind of sweaty, unrestrained chaos—highlighted by the vocalist jumping into the crowd and hyping everyone up, ending the set with a broken finger that somehow only amplified the legend of the moment.

Norway’s Susperia turned the temperature up with their melodic thrash attack. Their songs explore life’s battles, internal struggles, and fractured relationships, and their tight, punishing riffs hit the audience like a hammer, leaving them craving more.

Sweden’s Necrophobic followed, transforming the stage into a cathedral of darkness. Known for exploring anti-Christianity, death, satanism, and darkness, they emerged in masks, radiating menace and turning their set into a theatrical ritual that perfectly embodied their themes.

Dutch death/doom giants ASPHYX then unleashed a relentless set drenched in themes of torture, damnation, death, and war. Their crushing wall of sound primed the audience for the grand finale of the night.

Closing out day one were the Finnish melodic heavy metal icons Amorphis. They brought myth and metal together, channelling the Finnish Kalevala into soaring, majestic riffs. Their set was a powerful mix of beauty and aggression, a triumphant performance that left the crowd ecstatic as they spilled into the night.

Day Two: The Sound and the Fury

The second day began with What Is TEC?, a Turkish modern metal band who got the crowd warmed up with an energetic set that encouraged movement and set the tone for another wild day.

Italy’s Sadist took the stage next, weaving their progressive death metal with dark Hitchcockian imagery and themes of perversion and mortality. The atmosphere turned darker and heavier, setting the stage for the next wave of chaos.

Germany’s Korry Shadwell stormed the stage dressed in black and commanded the audience with a blistering, high-energy set that kept the crowd engaged from start to finish. The pit was a sea of headbanging and chanting, the energy never dropping for a second.

Greek thrash metal force Suicidal Angels brought neck-snapping precision with songs exploring misanthropy, death, hate, and religious strife. Their set was pure aggression and left fans breathless.

Germany’s Obscura then delivered a clinic in technical death metal, blending philosophical and cosmic concepts into their intricate, virtuosic riffs. Their set was not only a performance but an intellectual challenge that rewarded careful listening.

Austria’s Belphegor brought one of the most theatrical sets of the festival, their stage transformed into a ritual space complete with burning sage and props representing death, blasphemy, and sadomasochism. Their performance was a sensory overload, equal parts shocking and mesmerizing.

Norway’s Old Man’s Child carried the torch with their symphonic/melodic black metal, faces painted in corpse paint and songs steeped in death, sorrow, and misanthropy. Their set felt like a dark ceremony that united the audience in its grim beauty.

Finally, Italy’s Lacuna Coil took the stage after 13 years away from Türkiye. Their alternative metal anthems about hypocrisy, darkness, love, and loss struck a deep emotional chord. Cristina Scabbia delivered a heartfelt speech encouraging positivity and resilience, a perfect emotional anchor for a performance that had the entire crowd singing every word. It was not just a set but a shared catharsis.

By the festival’s end, Istanbul was left buzzing. The Bosphorus Open Air Metal Festival was not just two days of music—it was a convergence of cultures, a celebration of diversity through heavy sound, and a reminder of metal’s power to connect people across borders.
