U2 may have fizzled a bit, ratings-wise, on their recent 5-night Letterman residency, and maybe they actually brought Good Morning America's ratings down when they did a live performance for the show last Friday, and perhaps their new album, No Line on the Horizon, has sold about 42% fewer copies than 2004's How to Dismantle an Atomic Bomb did in its first week. But that isn't stopping the Irish combo from creating a completely insane, War of the Worlds-style contraption to support their upcoming tour. The band's stadium performances will be "in the round," with a custom-made four-legged structure holding up the speakers, lighting and a large cylindrical screen, supposedly offering "an unobstructed view" to audiences. Except for the giant alien monster legs, which are also helpful for sucking up unsuspecting concert-goers and grinding them into sweet, sweet fan-pulp, to power our takeover of your puny planet. Bwah hah haa! You can check out a virtual tour of the thing over here. After the jump, "in the round" concerts: infuriating or just annoying?
