Yes, I totally missed it. Back from Arcade Fire at 1ish thursday night/friday morning, I was in a perfect postion to watch Titus Andronicus play Jimmy Fallon but a) I had work in the morning and, er, b) I didn’t know about it though i should have.
They played “A More Perfect Union” and killed it dead. here they are on Hulu (around 37 minutes in).
Play it loud.
