Country: Finland

Rotten Sound carry three decades of grindcore history on their shoulders, rising from the cold corners of Finland with a mission to grind harder, faster and louder. Formed in the early 90s, they grew from underground chaos into one of the most trusted names in extreme music. Albums like “Murderworks” and “Exit” set a high bar, and the band kept sharpening their edge through constant evolution. Vocalist Keijo Niinimaa’s harsh delivery, Mika Aalto’s cutting guitar work, and the crushing rhythm section have shaped a legacy that refuses to slow down. “Mass Extinction” comes as another firestorm from a band that treats short releases as concentrated blasts of truth.

“Mass Extinction” arrives as a tight salute to the band’s long run, charged with frustration toward the state of the world. Rotten Sound keeps their messages sharp, pushing through themes of polarization, exploitation and collapsing systems in a very straightforward way. The approach is simple, no padding, just harsh grindcore fired at full speed. The energy is instant, with Niinimaa throwing harsh warnings while the instruments storm forward with no hesitation. The atmosphere matches the subject matter, everything collapsing in fast motion.

The EP was born from the same sessions as “Apocalypse”, and it has that same stormy intensity. The production leans toward raw aggression without falling into chaos. Guitars bite, drums fire away, vocals tear through the noise. Every track hits fast and moves aside for the next wave. “Brave New World” stands out through its push for unity in a world that keeps splitting further apart. “Recycle”, “Idealist” and the title track keep the pressure high, each one hitting like a short hammer strike. Nothing drags, nothing stretches, it is straight grindcore presented without extra ornaments.

Rotten Sound remains a band that thrives under harsh conditions. Their music reflects the ugliness of modern society, but they channel it with precision and fire. “Mass Extinction” is a fierce addition to their catalog, short enough to work like a warning siren and heavy enough to sting long after it stops. It shows a band that understands exactly how to crush through noise and speak bluntly through extreme music. Their message is loud, the world is burning and time is running thin.
