If you've been following SiM or caught wind of this performance, you might be curious about what made this particular version special and why the band chose this platform for such a distinctive arrangement of their signature song.
We're here to walk you through everything that made this THE FIRST TAKE appearance noteworthy—from the expanded instrumentation to what it means for a song that has already surpassed 500 million streams worldwide.

What Makes This Performance Different
The most striking element of SiM's THE FIRST TAKE appearance is the arrangement itself. While "The Rumbling" is typically performed as a high-energy reggae-punk anthem with the band's standard four-piece instrumentation, this version incorporates a full choir and string section. For a song that's built its reputation on raw, aggressive energy and massive crowd singalongs at festivals worldwide, the addition of these orchestral elements creates something we don't often hear from SiM.
THE FIRST TAKE's format—recording artists in a single, unedited take—adds another layer of challenge and authenticity. There are no second chances, no studio fixes, and no safety net. What we see is what the musicians captured in that moment, which makes the decision to use such an elaborate arrangement all the more bold. Coordinating a choir and strings section in a one-take environment requires precision that goes beyond what most rock bands attempt on the platform.
The performance appeared as episode 719 of THE FIRST TAKE, joining a catalog that has featured everyone from J-pop stars to Western artists, all stripping their music down (or, in SiM's case, building it up) for the iconic white-studio setting.
Why "The Rumbling" Resonates So Widely
To understand why this particular song warranted such special treatment, we need to look at what "The Rumbling" has become since its release. The track served as the opening theme for Attack on Titan: The Final Season Part 2, one of the most anticipated anime conclusions in recent memory. That association alone brought the song to millions of viewers who might never have encountered SiM's music otherwise.
But the song's reach extends well beyond anime fans. "The Rumbling" has become a metal and rock anthem in its own right, generating enormous crowd participation at live shows around the world. The song's themes—dealing with overwhelming force, inevitability, and raw power—align perfectly with the apocalyptic imagery of Attack on Titan, creating a rare synergy where the opening theme feels inseparable from the show itself.
With more than 500 million cumulative plays reported across streaming platforms, "The Rumbling" represents SiM's breakthrough into a much larger international audience. It's the kind of track that introduces a band to listeners who then dive into their deeper catalog, discovering years of reggae-punk innovation they might have otherwise missed.
About SiM and Their Sound
For those coming to SiM through "The Rumbling" or this THE FIRST TAKE performance, it helps to understand where the band comes from musically. SiM is a four-member band from Shōnan, a coastal region in Kanagawa Prefecture known for its surf culture and laid-back beach atmosphere. That geography might seem at odds with their aggressive sound, but SiM has always blended seemingly contradictory elements—reggae grooves with punk aggression, melodic hooks with screamed vocals, and introspective lyrics with explosive energy.
Their reggae-punk style sets them apart in the Japanese rock scene, where genre fusion is common but rarely executed with SiM's particular combination of influences. The band draws from reggae, punk rock, metal, and hip-hop, creating a sound that can shift from a syncopated reggae rhythm to a crushing metal breakdown within the same song. It's this versatility that likely made them the perfect choice for Attack on Titan's intense final season.
The decision to add choir and strings for THE FIRST TAKE shows another side of the band's musical ambition—a willingness to reimagine their own work in ways that highlight different emotional dimensions of the song.
The THE FIRST TAKE Platform
THE FIRST TAKE has become one of the most prestigious platforms for musicians in Japan and increasingly around the world. The concept is deceptively simple: artists perform a song in one take, in a minimalist white studio, with no edits or corrections. What makes it work is the vulnerability and authenticity that format demands. We see artists as they truly are in that moment—their technique, their nerves, their raw talent all on display.
For SiM, appearing on THE FIRST TAKE represents a milestone in their career. The platform has featured some of the biggest names in Japanese music, and each appearance serves as both a validation of an artist's status and a showcase of their abilities under pressure. The fact that SiM chose to debut on the channel with an expanded, orchestral version of "The Rumbling" rather than a stripped-down arrangement shows their confidence and their desire to present something genuinely new to their audience.
The one-take format also creates a different kind of listening experience. We're not just hearing a performance; we're witnessing a moment of creation that can never be exactly replicated. Every breath, every subtle variation in dynamics, every small human imperfection becomes part of the permanent record.
