Eerdman has 1 Insane Clown Posse concert.

Insane Clown Posse (ICP), a Detroit-based horrorcore duo, was established in 1989 by members Violent J and Shaggy 2 Dope. Two years later, they formed the independent label Psychopathic Records. They've also created a unique multi-decade narrative with their Dark Carnival mythology, told through thematic album cycles called Joker Card Decks. The First Deck includes Carnival of Carnage (1992), Ringmaster (1994), Riddle Box (1995), The Great Milenko (1997), The Amazing Jeckel Brothers (1999), The Wraith: Shangri-La (2002), and The Wraith: Hell's Pit (2004). While still ongoing, the Second Deck currently includes Bang! Pow! Boom! (2009), The Mighty Death Pop! (2012), the two-part album The Marvelous Missing Link: Lost/Found (2015), Fearless Fred Fury (2019), and Yum Yum Bedlam (2021). ICP's fans constitute a unique subculture known as Juggalos, which are often identified by the Hatchet Man symbol and their shared love of Faygo, which ICP ritualistically sprays onto the crowd during concerts.
