"Halls of Illusions" is the first single by American hip hop duo Insane Clown Posse from their fourth studio album, The Great Milenko.

The lyrics speak about child abusers and woman beaters who take a hellish amusement park ride representing a fun-house to reflect upon their actions.

These illusions show what their lives could have been if they had chosen not to inflict violence and pain upon their families who have been destroyed by the abuse.

The clean version of the music video removes all language and graphic violence by changing the lyrics.

Slash (the Guns N' Roses guitarist) was featured in the song performing background rhythm guitar.
