A horrorcore rap duo that was originally a gangta rap group from Detroit known as the Inner City Posse. Growing up in a poor neighborhood, ICP (as they are usually referred to) resorted to crime to earn themselves some cash (Drug dealing, jacking, etc.). Both members (Violent J & Shaggy 2 Dope) dropped out of high school and eventually began rapping. They would record and release albums on their own with the little money they had. Their album Dog Beats got them on the local rap scene and after an apparent dream that Violent J experienced, they decided to change their name to Insane Clown Posse. Over the years, they released many albums, most of which revolved around The Dark Carnival (which is a mythical place thought up by ICP). Their unique style and attitude to say whatever they wanted and not care what anybody thought attracted many fans, who later would become a cult following known as Juggalos. ICP's lyrical talent isn't anything too special, usually not rhyming very well and mostly sounding childish. The appeal to their music is mainly the fact that they tell fictional stories through their music that contain lyrics about violence (i.e. "Since we out west I grabbed the shotgun, and blew his fuckin tongue out the back of his cranium") sex, drugs, necrophila, cannibalism, etc. They also use deep symbolism that most people are too ignorant to look into. ICP is possibly the most hated musical act in the world and possibly of all time. People can often be found on the internet going to every website possible simply to insult ICP and their fans. ICP themselves enjoy the idea of being the most hated rap group in the world because "at least their number one in something". ICP have been going strong since the early 90's with no sign of falling off and will probably continue to make music until they're dead.
