Placebo play anti-slavery gig at Angkor Wat.<br />Had there been a roof, Placebo would have raised it as they headlined the first rock concert in history at Cambodia's Angkor Wat temple.<br /><br />Some 1,200 fans of all ages, mostly Cambodian, watched the London-based alternative rockers top a bill on Sunday (local time) backed by musicians from Cambodia and across the world in aid of a campaign against human trafficking.<br /><br />"I cannot believe that in a supposedly civilised world this kind of heinous form of modern slavery still exists, and I truly believe that we can all do something to stop this," frontman Brian Molko said.<br /><br />"It all starts with caring and compassion."<br /><br />It was Placebo who predictably stole the show with a number of their greatest hits, including Meds and Teenage Angst.<br /><br />"I'm very happy it's mostly local people in the audience tonight," Molko said shortly before taking to the stage in his trademark androgynous make-up and long black hair.
