Joseph Frank Bruce (born April 28, 1972), known by his stage name Violent J, is an American rapper, record producer, professional wrestler, actor, and part of the hip hop duo Insane Clown Posse (ICP). He is a co-founder of the record label Psychopathic Records, with fellow ICP rapper Shaggy 2 Dope (Joseph Utsler) and their former manager, Alex Abbiss. Also along with Utsler, Bruce is the co-founder of the professional wrestling promotion Juggalo Championship Wrestling.

Bruce was born in Berkley, Michigan, as the last born of three children. His father, Richard Bruce, stole all of the family's money and left when Bruce was two years old. Joe's mother, Linda, was forced to care for him and his siblings, older brother Robert and younger sister Theresa, off the income she made as a janitor. At age seven, the brothers caught a butterfly, and both were fascinated by the vibrant colors and overall peacefulness of the creature. They kept the butterfly in a jar overnight, and intended to free it the following morning. When they awoke, the brothers found the butterfly had died, and felt as if they had committed a murder. The brothers made a vow that "one day, [they] will make it to heaven, so that [they] can [...] apologize to that butterfly face-to-face." On every Insane Clown Posse album and EP it reads "Dedicated to the Butterfly".

Bruce received all of his clothes from rummage sales, and his food from canned food drives held at his own school. After moving to Oak Park, Bruce met John Utsler, and his little brother Joey. He began his gang life by reluctantly getting involved in criminal activity in Royal Oak Township. Along with John and Joey, Bruce got heavily into rap music. In 1989, Bruce, as Jagged Joe, Joseph Utsler, as Kangol Joe, and John Utsler, as Master J, released the single titled "Party at the Top of the Hill" under the name of JJ Boys, but they did not pursue a serious career in music.

Bruce dropped out of school in ninth grade, and moved in with his friend, Rudy, in River Rouge. There he formed his own gang called Inner City Posse, which would terrorize people with Army-issued tear gas and steal car radios for money. One night, Joe's mother, who had just moved to Ferndale, had her house attacked by rival gang, Hazel Park Posse (HPP), from Hazel Park. Fearing for his mother's life, Joe fled to Bonnie Doone, North Carolina, a trailer park town just outside Fort Bragg, where his brother was staying with the U.S. Army. It was there that Bruce witnessed the open racism which would later emerge as the hate for bigots referenced in Insane Clown Posse's lyrics.

At seventeen, Joe returned to Ferndale. He was soon jailed, and the experience convinced him to get away from gang life. In 1989, after a short career in professional wrestling, Bruce and his friend Dale Miettinen Jr. recorded Intelligence and Violence on a karaoke machine, which marked the debut of Bruce's stage name Violent J. Joe bought his own karaoke machine and, along with Joey and John Utsler, formed the music group Inner City Posse, named after their gang. After the release of the album Bass-Ment Cuts, the group hired record store owner Alex Abbiss as their manager, and established the Psychopathic Records record label with him in 1991.

In 1989, Bruce recorded his first solo release, Enter the Ghetto Zone, using two cassette players. One played the beat, while the other recorded, and Bruce stuck his head between the two and rapped. In 2003, Bruce released his second solo release Wizard of the Hood, which was an extended reference to the "Wizard of the Hood" songs which he recorded on Inner City Posse's Intelligence and Violence and Dog Beats, and Insane Clown Posse's Carnival of Carnage. In 2009, Bruce released the LP The Shining, which was initially given away for free at the 2008 Gathering of the Juggalos before being nationally released. During ICP's GOTJ 2013 seminar J and Shaggy stated that they were wanting to do solo albums. On December 10, 2015, with the release of Phantom: X-tra Spooky EP two flyers were released. One for Shaggy 2 Dope's new solo album titled F.T.F.O.M.F. said to be released in 2016. The other flyer was for Violent J's new solo album titled Karma Forest said to be released in 2016.^{[citation needed]}

In 2023, Bruce collaborated on two tracks for the Saddle Up and Ride EP from alternative rock band The Lucid, composed of Sponge vocalist Vinnie Dombroski, guitarist Drew Fortier, former Megadeth bassist David Ellefson, and Raven drummer Mike Heller. Bruce appears on the title track as well as a cover of Faith No More's "Epic" retitled as "Sweet Toof" featuring new lyrics written by Bruce and Dombroski.

In late 1991, Inner City Posse changed their style, look, and name. Bruce recalled a dream of a clown running around in Delray, which became the inspiration for the group's new name: Insane Clown Posse. Upon returning home that night, Bruce had a dream in which spirits in a traveling carnival appeared to him—an image that would become the basis for the Dark Carnival mythology detailed in the group's Joker's Cards series. These stories each offer a specific lesson designed to change the "evil ways" of listeners before "the end consumes us all." Insane Clown Posse has a dedicated following, often referred to by the group as Juggalos and Juggalettes.
