Rapper Q-Tip, former leader of A Tribe Called Quest, was to Rock the Vote here on Sunday, but the show will be going on without him.
Moving up to headliner slot on the lawn of the William Pitt Union will be Pittsburgh rapper Wiz Khalifa or Trevor Menear, a young blues guitarist out of Chicago. Also on the bill is Donora, one of the finalists of the PG's Pittsburgh Rocks competition.
Along with the music, there will be a kiosks about the issues, info on the candidates and, of course, voter registration.
Heather Smith, executive director of the non-partisan Rock the Vote, says the '08 election has been its most successful campaign.
"Rock the Vote has gotten more than 1.5 million people registered - about three times what we did in 2004."
The free concert begins at 3:30 p.m.
