LCD Soundsystem may have been this year's most surprising reunion — given that they called it quits only four years ago — but the dance-rock group turned out to be the most cathartic way to end four long days in Grant Park. Balancing braininess with fun, LCD never sways too far to either end in their live show, providing the perfect and most stirring outlet for fans to leave it all on the ground as they danced out their final hours at the festival. While every moment felt like a highlight, the final half was particularly rousing, with James Murphy crooning "New York, I Love You but You're Bringing Me Down" like Sinatra, the dance break in "Dance Yrself Clean" jolting the audience alive and the festival's actual finale, "All My Friends," providing one of the weekend's most life-affirming sing-alongs.

First day one, then two, then three, and finally Lollapalooza 2016 wrapped up on Sunday (7/31). One of the biggest appeals of the day was the reunited LCD Soundsystem. There was also the still-going-despite-lineup-changes Bloc Party, everyone's favorite the-'90s-are-back pop rock band Third Eye Blind, and Flume, Flatbush Zombies, Haim, Mothers, D.R.A.M., FIDLAR and more. Pictures are in the gallery above.
