For the uninitiated, Low Voltage is the moniker given to a series of sparse, atmospheric deep dubstep releases from the Phantom Hertz label. Here, they offer a neat overview of the series to date, picking 25 of their favourites. For those seeking clandestine, subterranean thrills, it should be essential listening. Opening with the sub-heavy minimalism of Lysergene's "Hammer Fall", Best of Low Voltage flickers between stoned paranoia, spooky intensity and off-kilter bass pressure. Picking highlights is tricky - Reamz's intoxicating "Tapeworm" aside - but there's more than enough goodness to warrant further investigation.
