Isiliel Live in London: Gig Review
Isiliel Brings Arena-Sized Energy to The Underworld
There are some gigs where you can tell within the first few minutes that you're watching something special. Isiliel's London stop on the Moonbow Legion World Tour 2026 was absolutely one of them, with Himari taking to the stage at The Underworld and immediately creating a sense of scale that felt completely disproportionate to the size of the room.
The Underworld is dark, intimate and famously close to the action. When you're performing in a venue like this, the audience is right there in front of you, leaving nowhere to hide. Isiliel didn't just embrace that intimacy; the performance seemed to expand beyond it.
From the moment the show began, the stage presence, atmosphere and sheer confidence felt much larger than the venue itself. It was the kind of performance where you could easily imagine Isiliel stepping onto a massive festival stage in front of thousands of people and looking completely at home.
"It felt like Isiliel was performing for 5,000 people."
The Heavy Metal Citadel Take
Dark, Atmospheric and Surprisingly Powerful Live
Musically, Isiliel is difficult to squeeze into a single metal subgenre, and that's exactly what makes the project so interesting. The sound moves between atmospheric and post-black metal, darker folk influences and more melodic, almost pop-oriented passages, creating a contrast between beauty and heaviness that feels very deliberate. Live, those different sides of Isiliel's sound came together naturally rather than feeling like separate musical identities competing for attention.
The heavier moments brought the darkness and intensity you'd expect from a black metal-influenced project, while the more melodic passages opened everything up and gave the songs a sense of atmosphere and emotional depth. There is a theatrical quality to the music, but underneath that is a genuinely strong collection of songs that can shift from haunting and delicate to forceful and intense without losing their identity.
Himari's vocals were another major strength of the performance. Her voice has a distinctive character that fits Isiliel's dark, otherworldly aesthetic, but what stood out most live was her control and ability to move between the project's contrasting moods. Rather than simply sitting on top of the instrumentation, the vocals felt like an integral part of the atmosphere, helping to give the performance its sense of drama while still cutting through the heavier sections of the music.
The result was a performance that felt both musically ambitious and surprisingly accessible. Even if you're not someone who normally gravitates towards black metal or more extreme forms of metal, there are enough melodic hooks, atmospheric passages and theatrical elements to pull you in. For established metal fans, meanwhile, there's plenty of darkness and intensity to sink your teeth into.
"Beautiful when it needs to be. Dark when it matters. And seriously powerful live."
A Setlist That Took the Crowd Through Isiliel's World
The set opened with "Jodo Dokushou", immediately establishing the atmosphere for the night before moving through a selection of songs that showcased the breadth of Isiliel's sound. Rather than feeling like a straightforward run through an album, the set had a sense of progression, moving between darker, heavier moments and more melodic and atmospheric passages.
Tracks such as "Black Moon," "Umbral Exorcism," "Serpent's Aubade" and "Moonbow Legion" demonstrated just how effectively the project can balance its heavier influences with its more theatrical and melodic side. The result was a set that felt cohesive without becoming predictable, keeping the audience engaged as the mood shifted throughout the performance.
There is a sense that you're being pulled into something much bigger than simply watching an artist play through a collection of songs. Isiliel's performance creates its own space somewhere between metal, theatrical performance, dark fantasy and Japanese pop culture, and the music is what ultimately holds that world together.

Himari's Connection With the Audience Made the Night
One of the biggest highlights of the Isiliel London show wasn't simply what happened on stage. It was the connection between the stage and the people standing in front of it. Himari made a real effort to engage with the audience throughout the performance, helping to create an atmosphere that felt energetic, personal and genuinely interactive. As a member of NECRONOMIDOL, she already has plenty of experience commanding a stage, and that confidence was evident here too, with Isiliel serving as her solo project and giving her a different space to build her own musical world.
That audience connection is particularly important in a venue like The Underworld. When you're performing in a small underground venue, there is a much shorter distance between artist and audience, and a great performer can use that to their advantage. Isiliel absolutely did.
The energy coming back from the crowd helped elevate the entire performance, creating the kind of atmosphere that makes live metal so exciting in the first place. There was a sense that everyone in the room was part of the show rather than simply watching from the sidelines.
Japanese Metal Meets London's Underground Scene
One of the things we love most about the underground metal scene is discovering artists who might not yet be household names. That's particularly exciting when it comes to Japanese metal, a world that spans traditional heavy metal, extreme metal, visual kei, avant-garde projects and artists who blur the boundaries between music, performance and visual storytelling.
Isiliel sits comfortably within that spirit of experimentation. Yet seeing the project perform in London added another interesting dimension: a Japanese artist bringing a distinctly individual vision to one of London's best-known underground venues, with a crowd ready to meet it head-on.
Japanese metal meets Camden. Dark fantasy meets a sweaty underground venue. A highly theatrical performance meets a crowd standing just metres from the stage. It shouldn't necessarily work as naturally as it does, but that's precisely what made the night so memorable.
"The intimacy of the underground. The ambition of the arena."
Why Isiliel Should Be on Your Japanese Metal Radar
For anyone looking to explore Japanese metal beyond the biggest internationally recognised names, Isiliel is a fascinating place to start. The project has a distinctive identity that feels difficult to categorise, and that's a compliment.
Isiliel isn't simply trying to fit into an existing metal scene. The project has its own aesthetic language, atmosphere and approach to performance, making it particularly interesting for fans who enjoy artists that exist somewhere between established genres.
If your metal taste extends beyond straightforward genre definitions and you're interested in discovering artists who bring together darkness, theatricality, atmosphere and Japanese cultural influences, Isiliel is definitely worth checking out. After seeing this performance in London, we're even more curious about where the project goes next.
