Rotten Sound Announce New EP ‘Mass Extinction’

Take cover, metalheads. After outrunning the apocalypse on their last long-player, Rotten Sound are back with another destructive burst of politically-charged grindcore. On their upcoming 11th EP, the underground veterans’ worldview is more dire than ever. But Mass Extinction lays waste to all that’s plaguing our society. The album’s lead single, “Brave New World”, pushes for unity over division behind a barrage of blast beats and relentless groove.

“This is one of the most aggressive songs on our new EP”, says Rotten Sound. “‘Brave New World’ is about how misinformation, polarization, conspiracy theories and censorship has lead people into a state of distrust. Our strong sense of community has been replaced by skepticism and fear. The fight for coherent and reliable information is now a constant struggle”.

Watch the hellish video for “Brave New World” on the Season of Mist YouTube channel.

Few extreme metal bands have enjoyed the shelf life of Rotten Sound. The Finnish exports longevity is practically unheard of for grindcore. The band’s core lineup of guitarist Mika Aalto, vocalist Keijo Niinimaa and drummer Sami Latva have been banging heads since 2004. Their high-speed blend of classic D-beat punk and Swedish death metal has only sharpened with each successive stab in the studio. “Brave New World” shatters your speakers like the perfectly-timed throw of a Molotov cocktail.

All eight songs on Mass Extinction were spliced from the same radioactive Petri dish that birthed Apocalypse. But Rotting Sound’s whopping 11th EP is no half-life mutation. In just under 10 minutes, the band chew through a festering host of societal ills. Ushered in by an opening address from none other than Jim Jones, “Brave New World” warns against following party lines sown by divisive leaders. “Trust no one“, Niinimaa screams over rapid-fire blasts and bludgeoning riffs that send the opposition ducking for cover.

The video for “Brave New World” was created by Shaumbra ArtVisuals.

Rotten Sound are ushering in Mass Extinction with a tour of South America alongside their Season of Mist labelmates DVRK and Brazil’s very own Crypta.

Next year, the band will return to the grind with a fresh set of European headline dates in support of their new EP. Following this blistering ride with Repulsive Feast and Teething, Rotten Sound will return to the U.S. for a special set at Maryland Death Fest celbrating their classic albums Murderworks and Exit.
