息殺しビート潜む
忍び足一歩2歩
一人勝ちきっと理想 この狂った世の中に一言申す
耐え難きを耐え忍び
武士は食わねど高楊枝
しゅ しゅ
煙の様 消えてくflow
リリックは刀さ 言葉は刃
チャクラを込め口を塞いだ
素破、乱破、奪口
数ある呼び名を変えてきては時代繋いだ
SOS俺が払う火の粉
影に潜む赤い目のニトロ
陰と陽俺がミット持ったace
Coolに乗るビート上でgame
Yo, listen
Once upon a time
古の時代から居た
影に潜んで暮らしていた
雲隠れしてる 忍ばす刀

SO-SOの口から出たビートに乗ってる 俺らはそうBass Ninja
忍び耐える者 この己に対する 失意っての産んだ写輪眼
ライムの畑で捕まえてる 口語で歌ってるよ まるでサリンジャー
確実こなしていくJob 狙い定める手裏剣
そう煙に巻いてこの
刀みたいな言葉 令和に感じるロマン
車でひくような 時代がしてく淘汰
バットマンよりもジョーカー 街と街に放火
等価交換する兄弟 じゃなく戸愚呂兄弟 100%
忍者の生まれた国俺また操ってる言語
飛んでく世界 言ってるこんにちは
やばいなら伝わる磨いてくセンスを
Throw, 確実外さない俺らの手裏剣
Draw, 抜いた瞬間に全て決まる刀

Bass Ninja (feat. Red Eye & ACE COOL)
SO-SO
Produced by SO-SO, the new single "Bass Ninja" features two of the Japanese scene's most authentic rappers, ACE COOL and Red Eye.
Built around the heavy, razor-sharp bass sound that has become SO-SO's signature, the track reinterprets a "Ninja" motif through the lens of modern bass music and hip-hop.
The production features a striking interplay of floor-shaking low ends and high-tension rhythms, maintaining an overwhelming presence within a stripped-back, minimalist arrangement.
In terms of the rap performances, the synergy between Red Eye's raw, persuasive lyricism and ACE COOL's sharp, sophisticated flow is particularly noteworthy, adding profound depth and aggression to the track.
This high-dimensional fusion of bass music and Japanese rap, true electronic, hip-hop is a feat only possible for an artist like SO-SO, who has spent his career transcending the boundaries of genres and scenes. It is obvious that the final product goes beyond being a mere club track, leaving a lasting impression through a pure listening experience.
"Bass Ninja" stands as a testament to SO-SO's evolution as a producer and a fierce intersection of ACE COOL and Red Eye's unique identities, making it a singular work that radiates a distinct presence in the current scene. The music video was released on the same day as the track.
