STB STUDIO, a recording studio and creator group rooted in Niigata Prefecture, releases its first collection "STB MIX"! DJ TAZAWA has compiled a nonstop mix of great songs discovered and released from this studio by not only USU, a local Niigata hood star, but also veterans and young artists full of talent! It is a work that beautifully combines the "now" of Niigata. The first track is "MPR," a track co-produced by STB producers WooRock, DJ TAGA, and DJ KOL, with 8 "never miss rappers" relaying the mic. It is a work that presents a new "Niigata".
