Fluminense Football Club is a major Rio de Janeiro club whose supporters are known for loud, organised backing in the stands, and the bateria is the percussion section that leads their chants. Recordings like this one circulate among fans as ready-made stadium atmosphere for edits, watch parties and social posts, especially around big matches and derbies. The numbered title suggests it comes from a series of supporter recordings, and its appeal lies in that authentic match-day rhythm rather than a studio track.
