FARMINGTON HILLS, Mich. — For more than 20 years, the rap duo Insane Clown Posse has courted controversy by rhyming about depravity, brutality and insanity. Now it causes trouble by making fun of Miley Cyrus.

A few days ago, Insane Clown Posse, a pioneering act in a rap genre called horrorcore, was approached by Fuse, the music-oriented cable channel, to record its commentary for a roundup of supposedly shocking music videos. Though the rappers have enjoyed their increasing visibility on Fuse (where a second season of their television series “Insane Clown Posse Theater,” will debut on Wednesday), they were dismayed to find that those videos included nonthreatening artists like Robin Thicke and Adam Levine.

“How are we going to sit there and talk about how shocking Maroon 5 is?” asked Joseph Utsler, an Insane Clown Posse co-founder who goes by the stage name Shaggy 2 Dope.

His musical partner, Joseph Bruce, known as Violent J, added: “We had to do it I.C.P.-style or it would have looked bad for us.”
