Project Description

Held in the aptly-named Belgian town of Boom, Tomorrowland is one of the biggest electronic music festivals on the planet. Founded in 2004, the festival continues to grow year after year, expanding from one weekend to two in 2015. Organizers We Are One World are always on the hunt for imaginative ways to unite hundreds of thousands of fans from around the globe at this unique event. This year’s newest addition, the Atmosphere Stage is a huge, 32-metre high tent suspended from a gigantic, custom-built crane. With an all-star line-up, a ceiling glittering with thousands of lights, and a 2km long video net containing 120,000 LEDs stretched around its circumference.

Recognizing the impact of L‑ISA in creating powerful shared connections between artists and audiences, Tomorrowland worked with L‑Acoustics to design a mammoth 20.1 L‑ISA system to elevate the concert experience for festival-goers.

Sound Design Solution

To accommodate the production team’s wish for the LED wall to be the visual focal point of the Atmosphere Stage, the L‑ISA configuration comprised 18 arrays of four Kara each, stacked on a truss above the screen and filling 270 degrees of a carefully configured circle. An additional flown system of eight K1 per side, plus 24 KS28 subs completed the 360° panorama and provided the full on, low-end kick that is the hallmark of EDM. This highly flexible and modular configuration allowed for delivery of both conventional stereo and immersive content, with the K1 system providing left/right delivery and the L‑ISA Immersive Hyperreal Sound adding extra detail, dynamics and effects to the mix. Multichannel content was specifically created for the L‑ISA system by Jelle Neijs and Bart Revier of 3AM Media for Dutch company Q-Dance, who have hosted stages at Tomorrowland since 2005.
