April 2, 2026, marks the release of “Iron Sharp“, a collaborative single born from the union of SUIKEN, an iconic figure from the group NITRO MICROPHONE UNDERGROUND, and beatmaker MAHBIE.
Announced as a “double-name” track, this project is not a simple guest feature, but a true artistic fusion between two respected entities of the Japanese scene. SUIKEN, whose career is intrinsically linked to the golden age of Tokyo rap with his collective NITRO MICROPHONE UNDERGROUND, brings his sharp flow and unparalleled experience to the table. Opposite him, MAHBIE, a producer renowned for his rich textures and hard-hitting rhythms, provides a sonic backdrop worthy of the challenge. The title of the track, “Iron Sharp“, seems to evoke this mutual emulation between the rapper and the producer, aiming for surgical precision in both production and vocal execution.
