“The Sickness” also contains the group’s hit, “Stupify,” a live version of which appears on the recently released “WWF Tough Enough” album. That album also features Drowning Pool’s breakthrough hit, “Bodies.”

On its tour, Disturbed is performing material from “The Sickness” as well as some songs that may be used on the band's next album, according to the band’s publicist.

Prior to the Sept. 22 kick-off of its Music as a Weapon tour, Disturbed was scheduled to give a headlining performance at Boston's Sept. 16 Locobazooka festival. The group’s manager canceled the engagement following the Sept. 11 terrorist attacks, however, citing “extremely unstable travel conditions,” according to the group’s official website.

The Music as a Weapon tour continues on Thursday (9/27) in Corpus Christi, Texas.

Disturbed's set during Music as a Weapon is preceded by a film that “depicts the way society treats those who are different,” lead singer David Draiman said in a band press release. The film features footage of Sadam Hussein gassing his own people, Armenian genocide, the race riots of the ‘60s, images of the Salem witch trials and of the massacre at Wounded Knee, and scenes from Nazi Germany, according to the press release.

The film is followed by a brief bit of theater, during which Draiman is placed in a six-foot tall plexi-glass chamber and appears to be gassed to death.

“It’s basically the ultimate statement and example of how the world deals with people who do not fit in,” said Draiman in the press release, “how the world makes scapegoats, how the world justifies genocide and holocaust or anything else for the sake of purity and for the sake of conformity.”
