Ronnex’s Kupferkessel, which was released on July 11, 2025, is a gritty, poetic meditation on trauma, culture, and internal conflict that goes beyond simply being a boom bap song. This German-language single’s soulful, analog sound and incisive lyrics make it a hit across national boundaries. With its dusty drums, chopped samples, and intense emotional weight, the song sounds as lived-in as it feels.
Kupferkessel, which translates to “copper kettle,” is more than just a catchy moniker; it’s a symbol. Ronnex uses it to examine how alcohol can be both traditional and tempting. He depicts scenes of joy, sorrow, and internal conflict using striking metaphors and eerie imagery. The kettle turns into a vessel for the soul’s distillation of pain, introspection, and unadulterated truth, in addition to liquor.
His verses are vulnerable, introspective, and keenly observed; they flow like journal entries. It is told from the perspective of someone who has actually experienced it rather than merely imagining it.
Kupferkessel’s production style has its roots in hip hop’s golden age. Ronnex’s voice pierces through with emotion and groove, while sample-based textures, warm pad sounds, and hard-hitting drums provide that nostalgic ’90s boom bap energy. Every bar lands with purpose, the tone is genuine, and the flow is catchy.
Grit, soul, and rhythm are all that are present here—no studio glitz. Ronnex’s sound will sound familiar to fans of introspective hip hop by artists like Aesop Rock, Evidence, or Kool Savas.
Ronnex combines traditional style with contemporary spirit with Kupferkessel. The end product is a strong, relatable song that has a lasting impact. This is a must-listen for anyone who enjoys boom bap beats, emotionally charged rap, and real storytelling.
