As if proving a component of chaos theory, the stir of a "Butterfly" has caused some major tour happenings for rock-rappers Crazy Town.

With their debut album at #16 on the Billboard 200 — thanks in part to the hit single "Butterfly" — Crazy Town are the latest additions to this year's Ozzfest lineup, according to a spokesperson for the tour.

The Hollywood septet joins the previously announced roster of Black Sabbath, Marilyn Manson, Slipknot, Papa Roach and Linkin Park on the main stage (see [article id="1439031"]"Black Sabbath Will Headline Ozzfest"[/article]).

Fans can only hope this year's stint fares better than Crazy Town's debut run on last year's edition of the Ozzy-founded outing. In July, five shows into the tour, they were forced to resign their second-stage post after frontman Shifty Shellshock was arrested and jailed (see [article id="1427579"]"Crazy Town Leaves Ozzfest After Arrest"[/article]).

Meanwhile, Disturbed, who were reported earlier as a main-stage attraction, will now occupy the headlining slot on the second stage. No additional acts could be confirmed at press time.

The sixth annual Ozzfest kicks off June 8 in Chicago; Crazy Town last took top billing on a tour in November, when fellow Ozzfest 2000 alums Shuvel and Slaves on Dope served as openers.
