I'm yet to see them.
Would have been going to one of the Manchester shows in 2009 but a buddy of mine spent too long debating whether or not he could come, and of course, by the time tickets rolled around and sold out, he still hadn't made up his mind. I'll silently never forgive him for that, as the setlists looked perfect.
Still hopeful of course that Trent is persuaded to pull the old gear on and take NIN round the block a few more times once he's recharged his mojo with these other (admittedly awesome) side projects.
