Members of the Grateful Dead and the Allman Brothers Band will reunite tonight in the Bryce Jordan Center for a concert to involve people in efforts to "get out the vote."

Andrea Mead, spokeswoman for the Obama campaign in Pennsylvania, said the event is a reflection of how people are feeling across the state.

"This unprecedented reunion is just one more example of the urgency we're seeing across the country for change," Mead said.

The cost of the tickets will primarily go to cover concert costs and not to Obama's campaign, Mead said Sunday evening, adding there are about 400 tickets left.

"The real reason for this concert is the field aspect -- we expect to sign up hundreds of volunteers," Mead said.

The two bands approached the campaign, Mead said, eager to be helpful in this battleground state.

Members of the original Grateful Dead -- Bob Weir, Phil Lesh, Bill Kreutzmann and Mickey Hart -- are scheduled to perform, as well as those currently touring for the Allman Brothers Band -- Gregg Allman, Butch Trucks, Jaimoe, Warren Haynes, Derek Trucks, Marc Quinones, Oteil Burbridge and Jeff Chimenti.

An "army" of volunteers will also be present at the concert, working to get out the vote, Mead said.

Casey Miller, youth vote director for Penn State Students for Barack Obama, said she is scheduled to make a pitch for volunteers at the beginning of the concert.

"It's going to be a once-in-a-lifetime opportunity," she said.

Though she is a fan of the Grateful Dead, Miller said she is more excited for them to come to State College for Obama.

"The fact that bands are reuniting to play together shows how important [this election] is," Miller said.

She said the concert is a great opportunity to get people excited for the campaign.

"We really want to make everyone aware of our need for volunteers in the last couple weeks before the election," she said.

Familiar with the Grateful Dead, Miller said her parents listened to them and she has their songs on her iPod. She said a Jerry Garcia poster hung in her room when she was growing up.

Rep. Scott Conklin, D-Centre, said he will attend the concert to support the Obama campaign and to see the musicians.

Though Conklin said he enjoys the Grateful Dead's music, he said he does not consider himself a "Deadhead."

Conklin said he listened to the group on vinyl records, which he still has.

"I think this is just more about people just going out and enjoying the music," he said.

Greg Stewart, co-chairman of the Obama Pennsylvania field team, said he will attend the concert, but has "no official duties" today.

Obama has a variety of musicians supporting him, he said, including Dave Matthews Band, who played for the delegates of the Democratic National Convention in August.

Stewart said he had seen the Grateful Dead many times over the years.

"The first time I saw them was 1970," he said.
