HI-LO is the dark techno alias of Dutch DJ/producer Oliver Heldens, born in Rotterdam in 1995. The HI-LO project launched in 2016 as a parallel outlet for harder, more techno-forward material than the Heldens-branded house catalogue, and releases on Heldens' own Heldeep Records and the Lyase Recordings sub-label have followed steadily since.
Notable HI-LO releases include the 2017 "Renegade Mastah" collaboration with Sander van Doorn and ongoing collaborations with figures from the wider techno crossover scene. The project sits in the dark progressive / techno register that has overlapped increasingly with the late-2010s and 2020s mainstage trance circuit, and HI-LO sets routinely appear on the same festival mainstage rosters as classic-trance acts.
Sound Style
Dark, percussive techno with progressive-trance breakdown DNA — drops engineered for festival mainstage scale, harmonic content sparser than melodic-trance, rhythmic content denser than peak-time uplifting.
