Rock band Blue Mash fire another flare into the live-house skyline with 若者白書 (Wakamono Hakusho / “Youth White Paper”), a track aimed straight at “all young people” like a feedback-drenched manifesto stuffed into a school notebook. Built for sweaty venues rather than polite background listening, the single carries that classic coming-of-age band voltage: raw hearts, loud guitars, and the emotional CPU running dangerously hot.
