Natural Error make no mistakes when it comes to making drum and bass designed to be danced to. This new release sees the duo send their sounds down the sewer, with synths lines so acerbic they should only be heard underground. Lead track "Experiments" warns parents 'this type of performance' maybe shocking, and the resulting drop is nothing but. Initially "Simple" is a Japanese fluted roller, but a gnarly build soon enters and the mutant musicality returns. Keep these tracks on a leash.
