"It works for us because we know how to f---ing use it. We need to be getting [American troops] the f--- out of harm's way tomorrow and back to the United States," he added before leading the crowd in a chant of "U.S.A."

He waived his hand above the crowd to silence the "U.S.A." chant and the audience stopped on a dime--much like Disturbed's songs.

Disturbed focused on its latest album, "Ten Thousand Fists," during the first of the group's two nights at the Marquee Theatre. One thousand fists pumped in the air as Draiman struck a Jesus Christ pose in the opening minutes of the show.

After whipping through three staccato-laden songs, Draiman--whose voice was studio-ready throughout the night--addressed the crowd: "My brothers, my sisters, my blood: Speak to me." In reply, the crowd saluted him with fingers fashioned into devil horns.

Bass rattled the venue during "Fear," and Disturbed's cover of Genesis' "Land of Confusion" later filled the theater with Dan Donegan's circular guitar licks.

In another outburst, Draiman contended the United States has forgotten what rock is all about. He blamed rock's downfall on bands that start with "the"--Strokes, Vines, Hives, etc.--as well as "emo screamo" acts that get up on stage and sing about breaking up with their girlfriends and riding off on their skateboards.

"They're the ones who killed rock or dealt it a damaging blow. We're here to stop it," Draiman said. "Shall we continue with the real rock show?"

Toward the end of the gig, Disturbed unleashed a series of hits, ranging from "Stupify" to "Stricken," before closing the show with "Down With the Sickness."
