DENVER -- Rage Against the Machine will join the Iraq Veterans Against the War and Tent State University to perform as part of the "Tent State Music Festival to End the War" during the Wednesday of the Democratic National Convention.

The free concert for the politically outspoken rap-rock band will be held Aug. 27 at the Denver Coliseum, which is about three miles away from the Pepsi Center.

The Flobots, The Coup, State Radio, and Wayne Kramer -- who played during the Democratic convention in Chicago in 1968 with MC5 -- are also slated to perform.

"I do this out of a sense of participating in democracy," said Kramer, who said he plans to vote for Democrat Barack Obama in November. "Democracy requires participation. It's not just a theory."

All the artists donated their time to perform in Denver, event publicist Carrie Lombardi said.

"It is a peaceful protest through music," she said.

Rage Against the Machine also has a concert scheduled Sept. 3 in Minneapolis during the Republican National Convention in the adjacent city of St. Paul.

Doors open at 9:30 a.m., show begins at 11 a.m..

The 8,000 tickets for the concert are free and available by lottery. Sign up for the lottery, with a valid photo ID (person must be present) at Tent State University at Cuernavaca Park between 11 a.m. and 6:30 p.m. from Aug. 24 through Aug. 26. (Look for the Tent State Music Festival booth near the IVAW Tower.)

Winners will be notified by e-mail Tuesday evening, Aug. 26.

The Democratic National Convention will be Aug. 25-28.

Cuernavaca Park is Tent State University's base for the convention.

Tent State University describes itself as a college campus-based movement aimed at ending the Iraq war.

The group originally sought to camp at Denver's 314-acre City Park during the convention, but the city said a park curfew would prevent anyone from staying overnight.

Tent State then decided to move to Cuernavaca Park, which is smaller but closer to the Pepsi Center, where most of the convention will be held.

Kramer said he and Tom Morello of Rage Against the Machine have long worked together on music and activism.

"When the opportunity came up to take our electric guitars and make some unholy noise to try to stop a war, it sounded familiar to me," Kramer said. "It's something we did 40 years ago, as part of a generation that said the war in Vietnam was wrong and needed to stop. We're part of a generation saying the war in Iraq is wrong and needs to stop."

He hasn't performed during a Democratic convention since 1968 in Chicago, marred by clashes with police. Kramer said he had no expectations of what would happen in Denver.

"I'm going into this with positive energy and hope of nonviolence, a commitment to reason," Kramer said.
