Pioneers of death metal in Portugal, SACRED SIN carry a legacy of brutality and innovation that dates back to 1991. Influenced by the aggressiveness of north american death metal and the darkness of European metal, they quickly stood out with a dense and powerful sound, filled with razor-sharp riffs and lyrical themes exploring death, darkness, and social criticism. Their debut CD, «Darkside» (1993), opened the doors to the European underground, establishing them as one of the most influential bands of the genre in their homeland. Throughout the decades, they have released a solid discography, with standout works such as «Eye M God» (1995) and «Born Suffer Die» (1999), showcasing compositional maturity without losing their characteristic ferocity. After a hiatus, they returned with renewed strength and have maintained a consistent activity, continuing to influence new generations of musicians and fans. At SWR 2025, SACRED SIN promise a show packed with heaviness and nostalgia, celebrating their extensive career and reaffirming their status as pioneers of extreme metal in Portugal.
