Members of the Grateful Dead will reunite for a historic one-time show next Monday at the Bryce Jordan Center in support of Barack Obama's presidential campaign.

The concert, entitled "Change Rocks," will also include members of The Allman Brothers Band. Tickets are $50 for the public and $30 for students with an ID and were still available as of press time.

Four original members of the Grateful Dead will be performing at the show: Bob Weir, Phil Lesh, Bill Kreutzmann and Mickey Hart. The current touring lineup for the Allman Brothers Band -- Gregg Allman, Butch Trucks, Jaimoe, Warren Haynes, Derek Trucks, Marc Quinones, Oteil Burbridge, and Jeff Chimenti -- will also be playing.

Rather than raising money for the campaign, the concert is being held specifically to generate interest in Obama's cause, said Andrea Mead, press secretary for the Obama campaign in Pennsylvania.

"The purpose is for a field organizational component for the campaign," she said. "We're trying to get a message out. The cost of the ticket actually just covers the cost of the event and doesn't go to the campaign. The actual goal is to get people together in one place. We'll be using the concert to help sign up people to help us with the 'Get Out the Vote' effort."

The show is a kind of sequel to one held last February in San Francisco, Mead said. That performance, which was called "Deadheads for Obama," marked the first time since 2004 that Lesh, Weir and Hart had performed together. Kreutzmann will be joining those three for the BJC show.

Both groups playing Monday peaked in popularity during the counterculture movement of the late '60s and early '70s. Greg Gabbard, owner of City Lights Records, 316 E. College Ave., said the Dead's participation in the campaign effort is appropriate considering the band's reason for reuniting.

"They haven't played together for a long time, so this is pretty significant," Gabbard said.

Zachary Zabel (sophomore-geography), president of Students for Barack Obama, said a desire to help make a difference is what convinced the group to reunite.

"They're coming together for a greater cause: Barack Obama," Zabel said.

The concert being held in State College highlights just how important Pennsylvania will be in the upcoming election, Mead said. The bands originally suggested the location, and State College made sense for campaign efforts with its central location in the state.

"They asked where and how they could be helpful," she said. "They said they had a huge fan base in Pennsylvania. Also, Pennsylvania is a battleground state."

The San Francisco show was a private endeavor by the band to raise awareness for Obama. Mead said following the success of that show, the members of the group inquired about the possibility of joining forces with the Obama campaign for a future show, which led to the idea for a show in Pennsylvania.

Zabel said State College is perfectly situated so that a large number of Pennsylvanians can attend.

"The Bryce Jordan Center is a huge venue and in a great location in the center of the state," Zabel said.

He added he believes the concert will inspire people to travel to the event.

Students for Barack Obama will be heavily involved at the show, Zabel said.

"Most members will be volunteering at the event, passing out literature and recruiting volunteers," he said.

Some Penn State students were excited at the prospect of two legendary bands choosing the BJC for a concert, but the politics of the show left some feeling betrayed.

"I think it's amazing that they want to get together to perform here," Kacie Long (freshman-engineering) said. "The convenience of it is great. With that said, I am not sure that I will attend the concert. They are taking advantage of people's love for their music to spread their own political views."

Despite her reservations, Long said the ticket cost was surprisingly low for such high-profile musicians.

Mead said she expects a good turnout for the concert because of both bands' popularity.

"Obama supporters are

excited about the campaign and this concert building support for this grassroots movement," Mead said.
