"Kirby’s contributions certainly recall his solo project, Mount Carmel & The End Of The World, though seamlessly integrate into the band and record. It’s no coincidence that drummer Nicholas Pizzolato shifts forward in these tracks, as his bombastic drummer drives the liveliness."

I think that's what he was talking about.
