Frequency

Frequency is a name shared by several distinct entities, but the primary musical footprint belongs to the Spanish melodic death metal outfit from Albacete. Emerging in the mid-2000s, they transitioned from demo-stage experimentation to a professional, high-fidelity sound with their 2011 release 'Rotten Empire'.

Their sound identity is defined by the 'Sadman Studios' aesthetic: tight, compressed production, dual-guitar harmonies reminiscent of the Gothenburg school, and a rhythmic versatility that occasionally touches on groove metal and power metal. Culturally, they represent the professionalization of the Spanish extreme metal scene during the early 2010s. While other entities using the name include a Chicago-based AACM jazz quartet and an Indian experimental electronic group, the metal iteration remains the most prominent in digital playcounts. Their career arc shows a move from raw death metal roots toward a more 'flow-based' alternative metal style in later years, reflecting a broader industry trend toward genre-blending and melodic accessibility.
