Come one, come all, to a land under the sea, where mystery awaits and great beats are on deck -- Tomorrowland has revealed its dates and theme for 2018.
Every year, the magical three-day event centers its huge, storybook stage productions around a theme. In 2017, it was "Amicorum Spectaculum," the carnival of friends. Now, in 2018, will be "The Story of Planaxis." A planaxis is a genus of small sea snails, the ones with swirly shells, hence the Fibonacci sequence logo, which, with that staff sticking through it also resembles the bottom half of a Treble clef. A cinematic trailer reveals Planaxis as an underwater city, a thriving Atlantis of magical proportion, which you can watch below.
