Hayes Collective is an influential underground techno label from Portugal, known for its high-energy, polished sound and consistent output, with 75 releases since 2018. Nørbak's album Casa (2025) exemplifies Portuguese techno, featuring aggressive tones, clean production, and intricate rhythm patterns. Key tracks include Rosna, which balances organic textures and upbeat drum patterns, and Capital, showcasing a call-and-response motif elevated with a unique vocoded synth.
