Because the results could end up sounding like ProjectHuman, that's why. Just because the tracks Dieselboy is using on ProjectHuman are ultra-exclusive and commendably open-minded doesn't mean that they fit together well enough to generate a mix with a discernible theme -- or, in some cases, that they're any good at all. Although Dieselboy's mixing is as impeccable as ever, the track selection is all over the map. The Terminator-like "storyline," which he lays out in an incredibly hokey movie-trailer-style voice-over, never really pans out during the course of the session. The fact is, Dieselboy has always walked a fine line between having the freshest tracks and exercising discriminating taste, and ProjectHuman proves what we've always known: He had to slip eventually.
