The Six Joker'
s Cards are as follows: Carnival of Carnage, the Ringmaster, Riddlebox, the
Great Milenko, the Amazing Jeckel Brothers and the Wraith.
ICP named their six albums after each of the Joker's Cards and on each album is (at least) one song that explains what exactly the card means.
ICP claims to have been visited by the spirit of the Dark Carnival, who showed them six revelations in the form of the Joker's Cards.
ICP then made it their mission to spread the word, and tell everyone to change their evil ways before it's too
late, thus naming their six albums after each Joker's Card and putting a specific revelation into each. The first Joker's Card, Carnival of Carnage, was released in 1991; their final revelation, the Wraith, was released in
2004.
