If you were not among the lucky ticket holders for LCD Soundsystem’s final show at Madison Square Garden, then you have so far had to relive the experience through balloon photos and low-quality videos of Aziz Ansari crowd-surfing. Not anymore. Coming soon — at least to Sundance, and then presumably to the rest of the world — is Dylan Southern and Will Lovelace’s farewell documentary, which, by the looks of the trailer, includes a generous amount of footage from that last MSG concert. Also featured prominently, at least in the trailer: “All My Friends,” James Murphy close-ups, Chuck Klosterman’s voice, self-hugging pandas, the aforementioned balloons, and many feelings. Steel yourselves for this one. It’s a lot.
