This is not a concert, but an event: No fists-in-the air or Elvis pelvis here.
Members of Orbital are almost hiding behind their computer-driven instruments, which look like something out of WarGames. And the audience, well, the audience doesn't much care about what is going on onstage. People seem more interested in watching others.
Using the measure of a traditional concert, Orbital's full-house visit to the Trocadero Wednesday night - as an opener for industrial-dance act Meat Beat Manifesto - gets a thumb-and-a-half down. But this show by an up-and- coming British dance group may be a window to the future, with the concert as multimedia event where the crowd is as much a focal point as the artist.
