When it appeared Nine Inch Nails' Trent Reznor couldn't get any angrier, he did.

Reznor spewed a few scathing comments toward Delta Center owner Larry H. Miller and Mayor Deedee Corradini for keeping opening band Marilyn Manson from appearing onstage.A letter from Delta Center officials stated Manson's show had violated a clause in the booking contract that "prohibits indecent, obscene, immoral conduct, publicly obscene and lacking in good taste."

The letter went on to say ". . . after our research, we have found that the Marilyn Manson performance is offensive and unacceptable to our community standards."

The Delta Center's area manager, Scott Williams, said Thursday Manson's show was not in "anybody's best interest to be performed live onstage in Salt Lake City. If I had to do it again, I would do it the same way."

Nine Inch Nails was booked about six weeks ago, and the record agency added Manson when the tickets went on sale, Williams said. "Marilyn Manson hasn't had a career for an extended amount of time, and our research had to be done two days before the show."

Four Delta Center workers flew to Las Vegas Sunday, Oct. 16, to preview the Manson show at the Thomas and Mack Arena and told Williams they had become "physically uncomfortable during the show."

A press release from Formula Records, the record label for Nine Inch Nails and Manson, said the Delta Center letter listed as offensive some of the stage theatrics and dialogue including sexual devices on stage and merchandise with slogans including, "Warning, Heavy Metal Music contains satanic messages that will kill God in your impressionable teenage minds. As a result, you will be convinced to kill your mom and dad, and eventually, in all act of hopeless, suicidal, `rock and roll' behaviour(sic), you will kill yourself. Please, burn your records while there is still hope."

Lead singer Manson, who now goes by the title Rev. Manson, said, "this statement is simply a sardonic look at the level of absurdity political correctness has reached and right-wing Christian America's attempt to scapegoat rock 'n' roll for problems that originate within its own masochistic family structure. In short, it is a mirror. Sometimes your own reflection is the hardest thing to face."

Reznor, after agreeing not to allow Manson on stage, invited him anyway to make a couple of remarks during NIN's set.

Manson ripped up a Book of Mormon and threw it in the audience asking, "Do you let him (meaning God) run your lives?"

The audience of about 12,000 cheered.

Williams said he would never book Nine Inch Nails again.

"My responsibility as building manager increases as the age of the audience decreases," Williams said.

Corradini spokesman Thom Dillon was not available for comment.
