The offices and sound studios of Dex Audio look out over Macaulay Road in Kensington. I’m talking with co-founder Greg Williams, and he gestures at the footpath out the window where an impromptu crowd would gather to watch the ‘gig’ on the odd Saturday afternoon back in the 1990s. When Dex Audio was commissioned to produce an outdoor sound system, the audio engineers would have to test the rig in open space – so they would pull up the roller door and blast music out to the street.
