With a string of successful concept albums and several hit singles

With a string of successful concept albums and several hit singles, the band continued their grueling schedule and toured the United States again. Continued attempts by politicians and pressure groups to ban their shocking act only served to fuel the legend of Alice Cooper further and generate even greater public interest. Their 1973 US tour broke box office records previously set by the Rolling Stones and raised rock theatrics to new heights; the multi-level stage show by then featured numerous special effects, including Billion Dollar Bills, decapitated baby dolls and mannequins, a dental psychosis scene complete with dancing teeth, and the ultimate execution prop and highlight of the show: the guillotine . The guillotine and other stage effects were designed for the band by magician James Randi , who appeared on stage during some of the shows as executioner . In 2012 at Dragon Con , Randi and Cooper discussed their working relationship during this period. The Alice Cooper group had now reached its peak and it was among the most visible and successful acts in the industry. Beneath the surface, however, the repetitive schedule of recording and touring had begun to take its toll on the band.
