For the past two weeks, the most intriguing rock tour on the road has been something called Vote for Change.

The tour, unprecedented in complexity and the number of big musical acts involved, has been crisscrossing the tossup states in this year’s presidential election with a mix of music and an anti-President Bush political message. Doing as many as six concerts on the same night in states such as Pennsylvania and Ohio, it has included artists with a wide range of musical styles from rockers such as Bruce Springsteen and the E Street Band, R.E.M. and Pearl Jam, to folkie James Taylor, blueswoman Bonnie Raitt and country singers the Dixie Chicks.

On Monday, Vote for Change will have its last concert (and the only one where all the musicians involved will appear) in Washington, D.C. Sundance, a premium cable channel, will televise the event live in most of the country. It will be carried live at 7:30 p.m. on radio, satellite radio outlets such as XM and Sirius, and a Webcast through RealNetworks.

Sundance will frame the concert with film segments on the Vote for Change tour crafted by documentary filmmakers Albert Maysles and D.A. Pennebaker. Joel Gallen — who did the brilliantly conceived and executed “A Tribute to Heroes,” the live post-Sept. 11 telethon — will direct the concert coverage itself.
