John Dent's mastering credits include seminal albums by everybody from Bob Marley (never let it be said that one man is an Island), to Grace Jones to Motorhead to The Stranglers and a whole lot more. To answer the question 'Why even bother mastering?' John endeavoured to reveal some of the mysteries of the process, and conjured up a fantasia land of sound. When the man steps into his mastering studio, he hears things it's impossible to hear anywhere else: "When I'm in my room I can hear what workstation was used, how long the cables were that were used: things you can't hear in a normal listening environment."
