Long before computers did in fact conquer the world, the influential German electronic group Kraftwerk calculated that probability, contemplating the changes to come by harnessing the latest musical gear and technology to create enduring work that soundtracked the birth of the Digital Age. On Sunday night, the quartet made its Hollywood Bowl debut by offering an overview of its career, including the metronomic 1974 classic "Autobahn," the menacing antinuke song "Radio-Activity," the genre-defining electro classic "Trans-Europe Express," the important synthesizer pop gems from the group's album "Computer World" and more. Mesmerizing to experience in the open air, the band looped bloops and beeps, thumps and bumps and sibilant fake high-hats to play songs once described by Detroit techno producer Carl Craig as "so stiff they were funky." The show was accompanied by 3-D visuals that locked image with music and required the 17,000-odd fans to don glasses, making the crowd seem teleported from an Atomic Age movie theater. The sight and sound presented a persuasive argument on the band's enduring influence, even if it revealed the ways that, like the beige and boxy early-era personal computers, the march of time renders even the most innovative technological expressions obsolete.
