Yesterday, TomorrowWorld announced Hardwell as their first headliner for 2015. As mentioned earlier, TomorrowWorld will be announcing 13 headliners prior to their festival lineup.
For their second headliner, they have announced the King of Trance, Armin van Buuren. As announced in the video, Armin van Buuren has “found the Key to Happiness” and is getting ready for the festival. For van Buuren, the Tomorrowland/TomorrowWorld family is very special to him as his wife gave birth to his son, while he was performing his set at Tomorrowland 2013 in Belgium.
