Rise Against has announced that they will soon be touring with Rancid. The band had this to say:

Few things are more exciting than watching Bush finally release America as his eight year hostage, but if anything could rival that news, it’s this: We are more than pleased to announce that we will have the honor of touring the US & Canada with punk rock legends RANCID this summer. If Tim Armstrong didn’t confirm it personally backstage in LA a few weeks ago, we wouldn’t believe it either.

Tour dates have not been announced yet but are expected soon.
