The sixth annual Gathering of the Juggalos was the last Gathering held at Nelson Ledges Quarry Park. Tech N9ne, Mack 10, 2 Live Crew, Powerman 5000, Manntis, and Mini Kiss all performed. Charlie Murphy was also brought in as one of the stand-up comedians. The event also concluded the long running Underground Psychos contest which, through the votes of juggalos, added a new group to the record label. Both groups (Playaz Lounge Crew and Axe Murder Boyz) performed, and the winning group (Axe Murder Boyz) got to perform twice. Juggalo Championship Wrestling held an event called "JCW vs. TNA" which pitted JCW wrestlers against TNA wrestlers.
Quarry Park's owner, Evan Kelley, kicked the festival off his grounds later that year. He stated that, "Psychopathic Records broke some of the rules set down for the 2005 event, including blasting music all night long." He also explained that, "Drugs, alcohol, nudity, profanity and trash also became serious problems."
