22. LCD Soundsystem, 'Sound of Silver' (Capitol/EMI, 2007)
LCD Soundsystem's James Murphy fused Eighties synth-pop, dance-punk and Detroit techno into a staggering work of heartbreaking genius. Earlier in the decade, his DFA label had helped get indie-rock kids on the dancefloor with songs like the Rapture's "House of Jealous Lovers." Here he had those same kids shuffling their Converse to the electro of "Get Innocuous," laughing their asses off to the Euro-baiting boogie of "North American Scum," and crying in their craft brews to "All My Friends" and "Someone Great," reflections on aging and regret set to gorgeously throbbing synth grooves. Sound of Silver recalled albums like the Pet Shop Boys' Introspective, which used dance grooves to explore complex feelings of desire and obligation.
