Billy Bragg, Lupe Fiasco and Mos Def will join Rage Against The Machine star Tom Morello and Steve Earle for a protest outside the 2008 Republican National Convention.
The musicians will perform at the Take Back Labor Day Festival, hosted by the Service Employees International Union's on 1 September (08) in St. Paul, Minnesota.
The protest show will take place within earshot of the political convention, which begins on the same day.
