You can call it a sign of the times. But it’s more accurate to call it a series of signs that reflect our times. Several recording stars are teaming up to express their thoughts on the world’s political scene. They have posed for photos featuring protest signs that they made up themselves, The Associated Press reports. Among those involved is Public Enemy. You can probably guess what their sign reads: “Fight the Power.” Others involved include Modest Mouse, R.E.M., Death Cab for Cutie and Rage Against The Machine. The signs will be auctioned off starting next Tuesday. Proceeds from the online sales will go to benefit War Child International, a nonprofit organization that helps kids in areas of conflict around the globe, AP reports.  See the auction signs here.
