As one half of the influential production team and record label DFA, James Murphy has helped shape the sound of post-millennial dance music, from the Rapture's debut album to the series of vinyl-only singles DFA has released since 2002. He smartly saved some of his best ideas for his own "band," LCD Soundsystem, whose records are perhaps the dance music equivalent of Spy magazine in the 1980s -- hip, ironic, and blessed with an awareness of just how seriously so-called trendsetters can take themselves. A prime example of Murphy's arch wit is the first single, "Daft Punk Is Playing in My House," in which he imagines throwing a party cool enough that the enigmatic French duo would perform. And like Daft Punk, LCD Soundsystem know how to get the party started. Most songs consist of a single, sparse riff to which Murphy slowly adds layer upon frenetic, hypnotic layer. What begins as minimalist funk often ends with brilliant cacophony: synthesizers squelching, cowbells clanking, and Murphy chanting over the top. Those songs that don't adhere to this well-executed formula come off like experiments in stylistic replication: "Never as Tired as When Waking Up" apes Radiohead circa The Bends, and the album closer, "The Great Release," could be an outtake from Brian Eno's Taking Tiger Mountain (by Strategy). For that matter, Murphy seems to be doing an imitation of the Fall's Mark E. Smith -- with a severe cold -- for half of the album. With all this posing, should we be taking any of this overt snarkiness seriously? Of course not, but neither is he, and when it's this much fun, who cares? As good as the album is, even better is the essential bonus disc that collects all of LCD Soundsystem's 12" singles: two versions of the manic, epic "Yeah"; the punk-funk of "Give It Up"; and Murphy's hilarious debut single, "Losing My Edge," in which an aging hipster worries he's not as cool as he once was, while claiming to have been present at nearly every important musical touchstone of the last 30 years. We probably wouldn't want to be stuck talking to such a character at a party, but we'd let him DJ any day.
