Though Wishmountain is one of Matthew Herbert’s lesser-known aliases, its rigorous focus on sampling makes it a crucial distillation of his artistic practice. Wishmountain’s clattering 1996 debut, Radio, was sourced entirely from samples from a broken radio, while 1998’s Wishmountain Is Dead worked the sounds of jam jars, potato chips, and a cheese grater into bumptious minimal house. A decade after running rampant through a British supermarket chain on 2012’s Tesco, Wishmountain heads underground—literally. Stonework: 1000 Metres Down was stitched together from a sample library recorded at a former coal-mining site in Essen, Germany. Though it’s anyone’s guess exactly what materials are in play, Herbert’s textural sensibilities and relentless percussive thrust do a great job of translating last century’s heavy industry into today’s heaving dance floors. Gravelly and austere, cuts like “Hammer” and “Tool” make for hypnotic listening, while wrigglier cuts like “Deep” and “Headrush” flash back to the glory days of minimal techno at its most skeletal.
