Nothing elseZa Kuromaniyonzu

This is the opening track of the album “ACE ROCKER,” released in January 2012, written and composed by Masatoshi Mashima.
It’s insanely cool in its stark simplicity, stripping away all unnecessary explanation to bottle that raw, early impulse of “just do what you want.” The commitment to recording the entire track in mono is impressive too, giving it a punch where Hiroto Kōmoto’s vocals and the band’s sound hit you like a solid mass.
Don’t overthink it—just surrender yourself to The Cro-Magnons’ pure rock ’n’ roll.

This song is included on their 17th album, HEY! WONDER, released in February 2024.
Written and composed by Hiroto Kōmoto, it features a romantic worldview where a love for music intersects with the sparkle of romance.
The contrast between the monaural recording’s characteristically solid, block-like sound and the heart-wrenchingly wistful melody powerfully stirs the listener’s emotions.

to liveZa Kuromaniyonzu

The ending theme song “Ikiru” from the drama “Mr.
Hiiragi’s Homeroom” starring Masaki Suda is the 17th single, released in 2018.
The drama itself was a bit scary, but the yearbook-style visuals set to this track felt like a lovely page of youth, creating a curious balance.
From the very first line, the song has a strong Cro-Magnons flavor, and it’s straight-ahead punk rock that hasn’t changed since their debut single—no, even from before then.
With its fierce beat and messages that hit you in the heart, it’s a number that makes you think, “Punk is awesome!”
