45:33

Beat junkies familiar with the jumpy New York dance-punk of LCD mastermind James Murphy may be startled by 45:33's spacey title track (which actually runs a little longer than its name suggests). Originally commissioned by Nike, this hypnotic electronica suite steadily ebbs and flows, constantly morphing into tantalizing new shapes. Pleading soul vocals and whomping disco grooves give way to shimmering synths and bells, followed by eruptions of energy, and on and on. With its epic sweep, "45:33" has an ethereal quality conducive to late-night introspection or dance-floor catharsis—even if you're not under the influence. Murphy rounds out the 72-minute set with three other rave-friendly tracks, including the clattering "Hippie Priest Bum-Out."
