This morning, the four finalists of NBC’s smash hit, The Voice, took the stage at Universal CityWalk’s “Tower 5” venue to perform for fans one last time before next week’s season finale. However, this wasn’t the only fun these contestants had at Universal recently— before the final four contestants were announced, the eight semi-finalists recently were treated to a behind-the-scenes sneak peek of Universal Studios Hollywood’s epic, new thrill ride, Transformers™: The Ride-3D, set to open officially on May 25, 2012.
