I think the appeal of the Arcade Fire can be entirely summed up in the first 45 seconds of "Power Out (Neighborhood #3)," which is probably the most exciting intro of any radio hit that I've heard in the last five years or so. Every time I hear it on the radio (it still gets regular play on both The Verge, XM's indie Can-Con channel, and WFNX), I pretty much have to stop whatever I'm doing for the next five minutes, because it's one of those songs that demands attention both in its groove -- the Talking Heads comparison is quite correct -- and in the depth of its arrangement. Among other virtues, this song has the single most rocking glockenspiel part in the history of popular music. While "Power Out" is the purest expression of all that is good about the Arcade Fire, its virtues are on display through the rest of their catalogue as well. The level of seemingly unfeigned sincerity and occasional tendency towards bombast links them to early U2 as well as the previously mentioned Springsteen comparison, while the overall sound of their records (that unusual instrumentation and highly detailed arrangements) ties them to another of my current favorite Canadian bands, Broken Social Scene: if the folks in BSS had any interest in writing songs with conventional hooks and verse-chorus structures, they would likely sound very much like the Arcade Fire. So that's the appeal. Modest Mouse: apparently, college kids still like weed. S
