A theater marquee for a poorly timed concert is drawing attention because it advertises "Explosions in the Sky" on "Sept. 11."

The sign at the Egyptian Theatre in downtown Boise promotes a concert by the group Explosions in the Sky, which has the unfortunate timing of taking place on the 10th anniversary of the terror attacks that killed nearly 3,000 people when hijacked planes crashed into the World Trade Center, the Pentagon and a rural Pennsylvania field.

Experts say thousands of New Yorkers still suffer from post-traumatic stress disorder from the two airplane explosions at the Twin Tower that could be seen from miles away on that clear morning.

"I think it's unfortunate that the band is being equated with the tragic events of 9/11 in 2001," Joy Hart, the booking manager at the Egyptian Theatre, told NBC station KTVB.

She has no idea how a photo of the marquee ended up on the front page of NBC New York’s website Thursday.

The timing of the concert on Sept. 11 is a fluke, she told KTVB.

"It is absolutely a coincidence," says Hart. "It's very typical that we get big concerts coming through here on Sunday nights.

“It's unfortunate that this band has to be equated to those events. They formed in 1999 and I'm sure this is something that they deal with on an ongoing basis,” said Hart.

Ticket sales have been steady and Hart says they have not had any complaints.

Hart is hoping the recent attention doesn't blight the upcoming concert, but the indie rock band has had to contend with 9/11-related questions before.

They released their second album in late August 2001, just before the attacks, called "Those Who Tell the Truth Shall Die, Those Who Tell the Truth Shall Live Forever."

The album's artwork features a plane shining a light on an angel, and includes a liner note that reads "this plane will crash tomorrow."

A few months later, guitarist Michael James was detained at an airport because his guitar case had a sticker with the same message.

The Texas-based group played Radio City Music Hall in April.
