Never known for their subtlety, Insane Clown Posse have unveiled a 27-minute trailer starring Vanilla Ice for the 2011 Gathering of the Juggalos, a four-day music and camping festival.

The clip opens with a 'Star Wars'-like intergalactic title sequence. Before long, Vanilla Ice and friends appear as aliens who say that humans have a lot of problems, but they do love music.

They proceed to announce the lineup for the 2011 Gathering of the Juggalos, which includes ICP members Violent J and Shaggy 2 Dope headlining the event. The narrator warns, "If you have a problem with Juggalos, you can stay home and sit on your dumb bitch a--!"

The 2011 Gathering of the Juggalos take place on August 11-14 in Cave-in-Rock, Illinois. In addition to ICP, other acts on the bill include Kittie, George Clinton + the P-Funk All-Stars, and rappers MC Hammer, Mystikal, Juvenile and Vanilla Ice himself.

And we're pretty sure Tila Tequila won't be showing up this year.

Insane Clown Posse have enjoyed a cult following for more than two decades. The face paint-wearing, hip-hop band once feuded with Eminem and performed at Woodstock 1999. The band is working on its next release, 'The Mighty Death Pop!'
