Well, this is almost a really good bill... almost. You can't throw darts at the great M83 or Tegan and Sara. The former are still riding high upon their masterwork, the double album Hurry Up, We're Dreaming, which still sounds as ravishing as it did a year ago. They've become an excellent live band, to boot. And Canadian sisters Tegan and Sara have continued their surprising but effective growth from indie mope-folk to purveyors of the purest synthesized pop. The twins' latest injection, "Closer," from their forthcoming album Heartthrob, is that perfect wave of nostalgia and pop, a song that surely will soundtrack movies made years in the future about this current decade. But terror lurks in the latter third of this bill: Vegas-concocted rock-star simulators the Killers. Perhaps the single greatest insult foisted upon the mainstream pop-rock listening audience at large since Milli Vanilli, the Killers have painted well inside the lines at every turn (even their name is brain-slappingly obvious), and in the process have stripped away everything that's vital and original and imaginative about rock 'n' roll. For some reason, it's paid them handsomely. Oh, so you liked that one "Mr. Brightside" song? That's nice. That was nearly a decade ago. Since then, the Killers have left behind a long, non-biodegradable vortex of junk, the musical equivalent of the Great Pacific Garbage Patch. Get to this show early, then get the fuck out.
