Hell, you can find elements of this background, this bundle of stylistic ideas, creeping into almost any space you like. Indie rock has always seemed strangely immune from its influence, as if young rock fans were all forced to make firm and final choices about whether they were going to side with commercial rock and emo bands or hip Brooklynites— but even here, you get acts like Best Coast and Wavves, with their nostalgia for certain kinds of pop-punk and emo juvenelia, the ones that came just before the haircuts got elaborate.
