Ton Johnson and Caste Of Killers co-founder Jason Hillman drop by Milwaukee Record HQ to discuss their experiences performing for "urban" and "mainstream" crowds, how black and white rooms differ, and why there isn't more overlap between the city's two stand-up scenes. Despite the heavy subject matter, Johnson and Hillman manage to pepper in some hilarious tales of triumph, cringing recollections of bombing, and an overriding hope the line between urban and mainstream comedians will continue to blur.
