APC has evolved over the years featuring members from a lot of different bands (NIN, Puscifer, QotS, etc...). Notably James Iha from Smashing Pumpkins. James is not on tour with them and Maynard mentioned that Iha would not be with them because he is getting ready for the Smashing Pumpkins "reunion" tour - which is already no longer the original lineup again lol because D'arcy said she still can't work with Billy Corgan.
I've seen APC twice, both times incredible shows. We had great seats with a fully unobstructed view closer to the stage and slightly above the floor crowd. Only strange thing, both times, you basically don't get to see him because he's odd that way.
Going to throw this out too. Their opening act which I'd never heard of. It is part APC and Puscifer. I was not sure what to think when they started playing, but even with their short set, I already liked them (They must have filmed Again and Again on this tour, because that is the exact stage setup we saw).
