That makes perfect sense, actually. I've been thinking the same thing. There's nothing wrong with Hill's arrangements, technically (they're actually - in all honesty - quite good), but they don't pop out at you as being incredible, which Phantom has been known for in the past.
Oh man, I saw them in San Antonio and I was a mess by the end of the show. It's such a unique concept and they perform it like only they can. It's incredible.
