When we saw LCD Soundsystem a few weeks back, it was a total hysteria. They had a million white balloons falling from the ceiling, white linen pants, a million instruments, neon tape on the floor, short-shorts drummer and ten thousand pounds of visceral energy filtered through James Murphy and shot straight out his microphone. We can only imagine how wild that must have been in the mud at Bonnaroo, everyone communally dirty, too. Though we are at our desks listening to this live set, our hearts are in the trenches.
