On a hot summer night in July, crowds of people gathered in a remote wooded area in front of a concert stage. Their faces were covered in clown makeup and their arms and legs painted with hatchetman tattoos.

By the end of the night, they'd all be covered in sticky, cheap soda.

This was the annual "Gathering of the Juggalos" in Oklahoma City, where thousands flock to see their favorite rap group, Insane Clown Posse (ICP).

The Juggalos aren't just ICP fans— they've built a cultural identity around the music, the rap duo, and what it represents. In turn, ICP has stood up for its followers as they've been harassed and profiled all over the country. Unwittingly, these two white rappers from Detroit have become some of the nation's most determined advocates for free expression.
