Ken is the DJ for The Underground. He is depicted as a music snob, and often looks down on others for listening to commercially popular music and harbours extremely elitist views especially with regards to independent bands.
Because this station is a pirate radio station, the signal strength varies across Stilwater, often dropping in volume when driving around and making the station impossible to access in some areas, especially towards the northeast end of the city, such as the Hotels & Marina or the Museum district.
Due to the dropouts, it is possible to narrow down the area from which The Underground is transmitted, or the exact co-ordinates are specified in the game files. It is transmitted through the lower radio tower on Mount Claflin.
