Portugal’s flagship hard techno platform scales into a 21-hour continuous system.

A Mainstage-driven rollout where high-BPM sequencing, B2B structures, and genre crossover lock into one uninterrupted flow.

Set for July 11 in Esmoriz, Sound Waves returns with a 21st anniversary edition engineered around endurance and intensity, running from 5 p.m. Saturday through 2 p.m. Sunday. The format stays uncompromising: one continuous cycle of hard techno and hard bounce, designed for sustained energy rather than peak-and-drop pacing.

The lineup balances current drivers and foundational names across the spectrum. Adrián Mills, Cloudy, Restricted, and Klofama anchor the new wave, while SPFDJ, O.B.I., Svetec, and Trym reinforce the legacy tier, positioning the event across multiple BPM ranges and stylistic branches, from industrial pressure to schranz-driven acceleration.

This year’s structure leans heavily into B2B configurations and hybrid sets, with combinations like KUKO b2b Johannes Schuster, Svetec b2b O.B.I., and SLVL b2b USH shaping transitions across the night. The result is a fluid programming model where individual sets don’t isolate—they connect, overlap, and extend momentum.

Hard bounce enters as a defining layer in the system, pushed forward by the 240KM/H movement, with Adrián Mills leading the charge. That energy feeds directly into the harder techno backbone, creating a continuous pressure curve rather than segmented genre blocks.

Local and regional presence remains embedded in the architecture. Ornella and Sheila represent the Portuguese axis, while acts like 6EJOU, Toxic Machinery, and RÆKKE b2b RØY expand the industrial and contemporary edge of the lineup.
Following a 2025 edition drawing 30+ countries, the festival returns with two stages and 27 performances, scaling up while keeping its long-form, high-BPM identity intact.
