The Weeknd and Bryson Tiller's moody R&B worlds collided on Thursday night, as they performed the "Rambo" remix live for the first time. The audience exploded with excitement once the Toronto crooner, who was the special guest at Tiller's Berlin show, surprised-entered the stage.

Along with performing the boastful Trapsoul cut, The Weeknd also treated the European crowd with Beauty Behind The Madness' chilling "The Hills." Tiller has a few more U.S. dates left on his Trapsoul Tour, which kicks off April 25.
