The American progressive metal band ERRA combines technical complexity with accessibility. In doing so, they don't forget to pound hard: on their seventh album Silence Outlives The Earth (2026), the riffs are so low that an extra line has to be added at the bottom of the staff. Their compatriots Currents played in our Ronda in late 2024 with their album The Death We Seek (2023), where it was once again striking that vocalist Brian Wille excels in both clean vocals and screams and grunts. Two support acts are joining them: Aviana (SWE, metalcore) and Caskets (UK, post-hardcore)!
