CONCRETE GREEN 12 Mixtape Drops with CD and Merch
The latest installment of the CONCRETE GREEN mixtape series is now available for pre-order, featuring 34 tracks from 47 artists across two discs. Physical CDs and branded t-shirts are also up for order.
CONCRETE GREEN 12, the newest entry in the long-running mixtape series, is now accepting pre-orders for both CD and merchandise.
The project brings together SEEDA, DJ ISSO, and she's rough as curators, continuing the series' tradition of highlighting underground Japanese rap talent. The two-disc release packs 34 tracks featuring a roster of 47 artists, creating an expansive showcase of the current underground hip-hop scene.
Notable inclusions are "SEEDA Presents RAPSTAR CYPHER 2025" with Worldwide Skippa, jellyy, VERRY SMoL, Siero, Reichi, and Tee Shyne, plus a remix of SEEDA's "Slick Back" featuring PUNPEE, Lisa lil vinci, jellyy, and NORIKIYO. The compilation spans production styles and artistic approaches, with beats from established producers like D3adStock and collaborations across the underground circuit.
For fans looking to own a physical copy, the CD comes paired with merchandise—a heavyweight 5.6-ounce Printstar t-shirt available in black and white, sized from M to XXL. Pre-orders are open until June 15 at noon, with shipments expected around late July.
CONCRETE GREEN has been a cornerstone series for documenting the evolution of Japanese underground rap, with each installment serving as a time capsule of the scene's current state. This 12th volume continues that legacy while introducing fresh voices alongside established names.
Both CD and t-shirt can be ordered through the official pre-order page.
