Broken Social Scene sounds like driving down an open highway on a sunny day in a car packed with people all chattering over each other. What a drive -- if you're in the mood for sonic and scenic overload. Building on the critical buzz from 2002's You Forgot It in People, these Canadians further craft a sound best described as thick. Airy, dreamy and sometimes unintelligible vocals blend in with melodic guitar, electronic ambience and eclectic instrumentation. "Windsurfing Nation" best exemplifies this style, with propulsive drumming, layers of noise and multiple vocal hooks happening at once, although "7/4 (Shoreline)" is a song for math-rock geeks and pop freaks alike, and "Hotel" has subtle swagger dance-punks can only dream of. Although the band's exhaustive sound can be exhausting, the moments when it all clicks make this album worth the hype.
