Prosthesis is Mind Spiders' darkest release yet, both in themes and atmosphere, and electronics feature more prominently in its eight songs than ever before. "Cold," "Ulcer" and "No Filter" hit a particularly doomed note, but the synths and drum machine provide a presence rather than drive the proceedings; if anything, Mind Spiders uses them as pace-setting devices for the guitars and live drummer to outrun, in sprints of strident downpicking and on-the-beat hi-hat/snare work. Even "Split In Two" — in which the digital tones create jarring tone clashes that bear a resemblance to Devo — also reflects the group's insistence on precision, a foil for the band to continue attacking the beat.
