After a tuxedoed farewell, a lengthy hiatus, a controversial reunion, a Christmas song, and a handful of shows in Brooklyn, James Murphy's New York indie-disco troupe LCD Soundsystem have returned. "Call The Police" and "American Dream" debuted on Zane Lowe's Beats 1 radio show yesterday afternoon before hitting streaming services, as promised, at midnight."Call The Police" is a seven-minute synth trip that borrows from Bowie and ends up remarkably close to their 2007 hipster anthem "All My Friends." It's an update for the faithful—there are lines about moving to Berlin, not wasting time with love, and "questionable views.""American Dream" is more histrionic still, a thick, synthy ballad. Again, it's an update of an old idea. A whole lot of LCD Soundsystem fans will hear Murphy singing "You took acid and looked in the mirror / Watched the beard crawl around on your face" and feel a sense of familiarity. When Murphy sings, "Oh, the revolution was here / That would set you free from those bourgeoisie / In the morning everything's clearer / When the sunlight exposes your age," it must feel like a warm blanket.Listen to both tracks below.
