Exhilarating spectacles will be taken to new heights Wednesday, Oct. 16 as Michael Jackson ONE by Cirque du Soleil teams with Gibbon Slacklines to showcase a record-breaking highline walk attempt from the exterior of Mandalay Bay Resort and Casino, 63 floors above the Las Vegas Strip.  As the kick off to the 2013 World Slackline Federation (WSFed) Slackline World Cup Finals taking place the following day inside the Michael Jackson ONE theatre, daredevil Gibbon athlete Andy Lewis will attempt to set the world record for the longest urban highline walked as he forges a 480-ft. high, 360-ft.-long slackline rigged from two of the Mandalay Bay resort towers running parallel to the Las Vegas Strip.
