British producer Mau'lin is a relatively new artist with a record for Diskotopia arriving on August 26. "Visitor," a bonus track from the digital version of his Quotient EP, trades in the type of complex techno that has populated Berlin's musical landscape for over a decade. Mau'lin's production adds a Detroit toughness to the dark, driving rhythms, as he twists a simple arpeggio riff into various guises along the way. Never overbearing the listener with too many elements, Mau'lin adds a sly, pitch-shifting synth phrase and a quiet, rumbling vocal sample as its counterpoint, bringing just enough variation to keep the arrangement on edge. What's more, an abridged version of the EP's title track has been paired with some psychedelic visuals, which can be seen after the jump.
