Bono and his (RED) charity are using street artists to raise awareness about AIDS.
The U2 singer has commissioned 17 artists to paint murals at selected sites in London, Paris, Berlin, Lyon, New York and Washington, D.C. Bono says, "Street artists have been raising the alarm in the fight against AIDS since HIV appeared -- from the streets of New York in the 1980s... There has been a lot of progress, more than many experts predicted, but not enough yet to put the sirens to rest. Young women continue to bear the brunt of this disease, and maddeningly, every week 6000 of them are needlessly infected. I’d call that an emergency. (RED) is the color of emergency."
