''The Amazing Jeckel Brothers'' is the fifth studio album by American hip hop duo Insane Clown Posse, released on May 25, 1999, by Island Records, in association with Psychopathic Records. Recording sessions for the album took place from 1998 to 1999. The album is the fifth Joker's Card in the group's Dark Carnival mythology. The album's lyrics focus on the 19 circles of hell, and the morality of man as he is torn between righteousness and evil, describing the Jeckel Brothers as spirits who juggle pulsating blood-covered balls, representing the sins committed during the mortal life of the dead.

''The Amazing Jeckel Brothers'' was the second studio album Insane Clown Posse released by Island, and features a more hip hop-based sound, as opposed to the rock-oriented sound of its predecessor, ''The Great Milenko'' (1997). ''The Amazing Jeckel Brothers'' features guest appearances by popular rappers Ol' Dirty Bastard and Snoop Dogg, and additional contributions by The Jerky Boys and Twiztid. Although the album was poorly received by critics, it debuted fourth on the ''Billboard'' charts, and was later certified platinum by the Recording Industry Association of America (RIAA). - Wikipedia
