The boundaries between pop, country, and western, and rhythm and blues were defined by geography and/or
race in the minds of the music industry, with pop assumed to be consumable by everybody. Country and
western was for white people in the South and the West, and rhythm and blues was for Black audiences.
Once it emerged, rock and roll would not only prove these boundaries to be based on false premises but
would also throw another into the mix: the age of the audience. With these ideas in mind, are there
boundaries in place between pop, country, western, and rhythm and blues today? If so, are they rooted in
geography, race, age, or something different? Try to use specific examples if possible.
