Bestial Mouths return with “HISS,” a new single offering a glimpse into their upcoming album, Dead Lines (Líneas Muertas).

The track explores themes of spreading hatred, collective anxiety and the fragility of identity within an increasingly divided society. Through the project’s signature dark sonic landscape, “HISS” combines industrial tension, haunting atmospheres and intense emotional depth.

With this release, Bestial Mouths open a new chapter in their artistic journey, pairing their powerful sound with a striking visual aesthetic and a critical reflection on the cycles of toxicity that continue to shape society.

Dead Lines (Líneas Muertas) will be released on September 4 via Negative Gain Productions.
