Pop Goes The News — Twisted Sister’s concert last month at Quebec’s Amnesia Rockfest is one the 80s rock band would like to forget.

In a blog post (Update: it was deleted shortly after this article was posted) on the group’s official website, a tour assistant known as Armadillo Terry slammed the music festival in Montebello, about an hour east of Ottawa. This year’s event ran from June 23 to 26.

“This festival sucked donkey balls. Big hairy brown donkey balls,” he wrote.

Lead singer Dee Snider, 61, supported Terry’s assessment. He tweeted: “I can tell you, @amnesiarockfest are a BAG OF DICKS! #FUCKEM.”

Although the festival site is only a 90-minute drive northeast of Montreal, Terry claimed the ride from their Montreal hotel took two-and-a-half hours.

Once in the rural town, Twisted Sister was unhappy with only being given one dressing room at the Fairmont Chateau Montebello.

“How they thought we would fit 15 crew, 3 video guys and 5 artists in a hot, stuffy 10×10 room is absolutely astonishing,” he complained.

“No mirrors. Some hand towels. Not even enough furniture for all five band members to sit down. And no access to a restroom. The toilet was down a flight of stairs, down a hallway…around a corner…and it was one toilet for about 300 drunk people.”

The band was unhappy with the amount of food and water provided — and shocked to see “Twisted Sister” misspelled on the dressing room door.

Getting to the stage, Terry complained, involved a golf cart ride to a dock, followed by a boat ride to the festival site. There, he was taken aback by the size of the stage where Twisted Sister was scheduled to perform.

“So Korn and Blink 182 get the human-sized stage, but Twisted Sister gets a stage the size of a gnat’s mammography plate,” he wrote. “That’s right. Big enough for gnat tits. What’s that you say…. Gnats don’t have tits? Sure, they do…just teeny tiny ones. How teeny tiny are gnat tits? Just slightly bigger than the FUCKING JAGERMEISTER STAGE AT AMNESIA ROCKFEST!”

Terry said festival organizers did not live up to the band’s rider (he contract that lists its requirements and demands). “I have never experienced such a lack of respect.”

Band members were driven to the stage through a crowd of “unruly drunken revellers,” Terry recalled.

“I can personally attest that this was the drunkest, most stoned crowd I’ve ever seen. Pot smoke so thick it would have choked Cheech & Chong.”

Terry also took issue with a “pimple-faced security guard” who had “a temper tantrum” when Twisted Sister band members used the washroom ahead of him.

After all this, Terry said festival organizers gave the group only 45 minutes to perform. They did seven songs.

“We passed a note to Dee explaining that the festival was literally pulling the plug on us, so Dee started to say the words ‘thank you’ and ‘goodnight’ when the KING of all douchebags reaches over and shuts down the sound board,” wrote Terry.

“That’s right, kids. Here is Twisted Sister, playing for the last time EVER in Canada, and not only would they not give us the respect of playing the last song (which lasts 2 minutes) but they cut Dee off as he was saying ‘Thank You and Good Night!’

“We can put up with terrible production. We can put up with lousy catering. We can put up with shitty dressing rooms, dirty toilets, small stages and poor treatment of us, the crew. But to disrespect the band by pulling the plug on the last single note without even letting them say the words, ‘Good night!’ is unbelievable.”

Rockfest founder Alex Martel told the Ottawa Citizen: “We try to give sets as long as possible.”

Terry also said the local crew “tossed” the band’s gear off the stage.

He wrapped up the blog post with some strong words for Amnesia Rockfest.

“Fuck your boat, fuck your tiny-ass stage, fuck your forty-five minutes and fuck your five bags of chips. Canadians rockers…go to Heavy Montreal next year instead–this festival doesn’t deserve your attendance.”

Terry also posted videos from the festival on his Facebook page.

Update: In a statement released late Tuesday, Martel said he was disappointed to read the blog on the Twisted Sister website. “We contacted the band’s team as soon as we became aware of these comments, and they immediately decided to remove the blog post outlining their dissatisfaction.”

Martel said no one from Twisted Sister contacted expressed concerns to him directly. “Even though I strongly disagree with their claims and the way they chose to share their views, I still have tremendous respect for this legendary band and I wish them the best in their future endeavours.”

Billy Talent, Rise Against and Blink-182 were among the acts tweeting thanks to Amnesia Rockfest.

Founded in 2005, Rockfest is billed as the biggest rock festival in Canada. Organizers said it was sold out this year, with close to 200,000 fans.

This year’s edition featured acts like Jane’s Addiction, Ice Cube, Limp Bizkit, and Canadian acts like D.O.A. and Sum 41.
