How astonishing visuals are revolutionizing concert experience

(CNN) -- Take away the 100-foot screens, the blasting lasers, and the holographic projections, and what do you have left? Tens of thousands of screaming electronic music fans with nothing much to cheer except a solitary figure, twiddling some knobs and occasionally raising his hand.

For EDM fans across the world, the festival and concert visual performances can be almost as crucial as the music -- transforming a DJ-set into an unforgettable, transcendent, multi-sensory experience.

In the hands of specialist artists, the lights, images and physical environment around the DJ are becoming an art form in their own right. Buoyed by the explosion of popularity of live electronic music -- plus technological advances like projection mapping, innovative VJ (video jockey) software, mushrooming visual computing power, andthose famous holograms -- these artists are now getting the chance to display their creations on a spectacular scale.

Here, we look at six of the names working behind the stage to turn festivals and concerts into unforgettable immersive experiences.

Comix -- Avicii, Swedish House Mafia, Alesso

Avicii's 2014 arena tour was a jaw-dropping spectacle -- glittering with laser-fire, pyrotechnics, and epic on-screen visuals -- that promised that the young artist could pack out arenas across the world just as well as more established names. The company behind everything on screen are London designers Comix, and for sheer mesmerizing hypnotism, give Avicii a miss and look at their work onSwedish House Mafia's ultimate "One Last Tour."

                   Strangeloop -- Flying Lotus, Skrillex, Erykah Badu

If anyone was born to take music visuals to cinematic new heights, it was David Wexler, AKA Strangeloop. The grandson of Academy Award-winning cinematographer Haskell Wexler and the son of Oscar-nominated production sound mixer Jeff Wexler, the L.A.-born artist has worked with dubstep star Skrillex (whose spasmodic performance visuals have also seen him recreated movement-for-movement as a giant robot), and "soul goddess" Erykah Badu. But it all started with his art school classmate Flying Lotus -- Wexler and the experimental music idol have worked together since 2008.
