When Cartoons Meet Heavy Metal: The Phenomenon of BOI WHAT

If you have spent any time scrolling through internet music spaces or metalcore forums, you might have stumbled across a wild, heavy-hitting sound project that makes you double-take: brutal, down-tuned guitar riffs, aggressive breakdowns, and blast beats paired with the unmistakable, high-pitched voice of characters like SpongeBob SquarePants or Plankton.

This is the world of BOI WHAT (the musical project of artist Eli Strobeck), a unique internet phenomenon that sits right at the intersection of extreme music, pop culture nostalgia, and modern artificial intelligence.

Is the Music Actually Made by AI?

A common misconception when people first hear BOI WHAT tracks like Plan Z is that someone typed a prompt into a generative AI music tool and let a computer do all the work.

In reality, the music is 100% human-made.

Eli Strobeck writes, records, performs, and mixes all of the instruments and baseline vocals himself. The guitars are real, the drums are meticulously arranged, and the structural songwriting follows the true traditions of heavy metal and metalcore.

So, Where Does AI Come In?

Artificial intelligence enters the process at a very specific, creative step: the vocal filter.

Instead of using a computer to generate a song out of thin air, Strobeck records his own harsh vocals as a reference track. He then passes those vocals through AI voice-conversion models. This transforms the timbre and pitch of his voice to sound like iconic cartoon characters—yielding the surreal, comedic, yet genuinely heavy juxtaposition of a cartoon villain screaming metal lyrics over crushing breakdowns.

Think of it like an artist using Auto-Tune. T-Pain didn’t let a computer sing for him; he used pitch-correction as a stylistic tool to create a brand-new vocal texture. Similarly, BOI WHAT uses AI voice filters as an instrument, treating technology as a paintbrush rather than a replacement for human creativity.

Why It Resonates

The project blew up across platforms like YouTube, TikTok, and Spotify, pulling in hundreds of thousands of monthly listeners. Beyond the initial shock value of hearing a childhood cartoon character deliver a brutal guttural scream, the project works for a few distinct reasons:

1. Genuinely Good Production: The novelty would wear off quickly if the underlying music was sloppy. However, the metalcore composition is tight, well-mixed, and holds its own musically even without the internet gimmick.
2. The Meme-to-Art Pipeline: Internet culture thrives on subverting expectations. Taking hyper-innocent media (like Bikini Bottom inhabitants) and dropping them into a genre known for angst and aggression creates a hilarious and compelling contrast.
3. A Conversation on Creative Tools: As debates around AI in art heat up, projects like BOI WHAT spark interesting discussions. They highlight a middle ground where technology doesn’t steal the artist’s job, but instead merges with human performance to unlock weird, unprecedented forms of expression.

The Takeaway

BOI WHAT proves that the future of internet-era music isn’t necessarily about machines replacing humans. Instead, it’s about what happens when creative humans take new, strange digital tools and push them to their absolute limits—giving us heavy metal anthems from characters we never expected to hear in a mosh pit.
