For nearly 40 years, English producer Mark Van Hoen has been making challenging music that eludes easy categorization under his own name, as Locust, and in the groups Autocreation, Scala, and Drøne. While his output has skirted around the fringes of IDM, techno, trip-hop, ambient, drone, and electropop, it has mutated these genres’ elements in distinctive ways, revealing a mind always questing for unprecedented sounds.
