The track is by the Eiji Trio Band, a hip hop band from Kyoto dedicated to GOOD MUSIC. The band is headed by EIJI (Dachambo), who had appeared in countless festivals, including an appearance at Burning Man. The track features represent Echizen's "MASSADAWG" who roars fiercely and authentic scratching from DJ AKAKABE, who was the first Asian champion in the 2004 DMC WORLD FINAL's battle competition. Allow "Brain Wash" to open your mind.
