For a guy who allegedly never wanted to be in a big band, James Murphy managed to put together a good one. LCD Soundsystem called it quits last year after three albums and a final, four-hour show at Madison Square Garden. This film spends some time with Murphy in the days before and after the show, and shows highlights from the concert, including an appearance by Arcade Fire. You do get a genuine sense that Murphy wants the whole thing to be over with, but he’s so damned good in concert that you wish he were kidding about quitting. The concert portions are terrific (only segments are shown). Their albums are great, but LCD Soundsystem goes to another realm when performing live. I’d like to think a couple of years off might recharge Murphy, but his demeanor here makes it seem unlikely. This is a very good movie, and a bittersweet one if you are a fan. It’s also worth noting that Murphy has an adorable French bulldog.
