A rock piece that gets you pumped just from the intro.

The guitar isn’t particularly difficult overall, but the tempo is fast and there’s a guitar solo, so practice until you can articulate cleanly.

The bass mainly sticks to root notes, but like the guitar, the fast tempo means you need to be careful not to drag.

The drums have both a high tempo and complex phrases, so it’s best to start practicing slowly at first.

The vocals in the original are quite high in key and fast in tempo, so if you’re determined to do it with a band, make sure to practice thoroughly on your own as well.

I’m captivated by the overwhelming sound and song structure.

Released in October 2024 to celebrate the 4th anniversary of “Project SEKAI: Colorful Stage! feat.

Its worldview poses questions about one’s raison d’être and the meaning of living, unfolding within an aggressive sonic landscape.

Even amid madness and chaos, glimpses of order emerge—this distinctive musicality is just phenomenal.

I think it’s a Vocaloid track that truly embodies “the quintessence of digital sound.”
