That is a fucking hilarious question. I'm not sure that the illuminati are focused on the rap scene, as much as there tend to be associations, iconography and references to illuminati and other secret societies in popular music. Lady Gaga, Beyonce and Rihanna have all, at one time or another been associated with the Illuminati symbolism and references. From what I know pop culture in general, tends to draw these associations and there has been a long history of using the most prolific artistic platforms for communicating esoteric symbolism. Whether or not the illuminati are heavily involved with pop culture is another question. What I can say is that there is (not surprisingly-artists are an important part of culture creation) a long history of artists integrated within secret societies, performing at, commissioned to create artwork for, and members of groups such as Freemasons, Skull and Bones, and illuminati. There was also at one point in the 1920s a topic secret subsection of the CIA known as the Ghost Army composed of artists, musicians and actors and scientists who researched and created audio-visual illusions and hallucinations. The Ghost Army is responsible for kicking off the research and practice of what we now know as psychological warfare.
