Surgeon's From Farthest Known Objects splits the difference between the breakneck techno of his '90s output and the ambient albums released under his own name, Anthony Child. Made on what he calls "old and unlikely hardware," all 11 tracks share a nearly identical palette of buzz and rumble; instead of traditional drum machines, he sculpts gurgling frequencies into gnarled sounds that serve as both percussion and melody. "z8_GND_5296" has Kompakt's T. Rex shuffle and "GN-108036" rolls like Robert Hood; mostly, though, these otherworldly rhythms are maps to a world of Surgeon's own invention.
