With a delayed start time and a somewhat drawn out intermission, it's about 3 hours.
that being said, and barring a few small technical issues they'll fix in no time, the show has never looked or sounded better. They now have doubled the size of the ensemble, many of whom also play instruments that they play throughout the entire theatre.
i was seated about 4 rows into the orchestra, and though the show is played all around the audience and retains that intimacy, it definitely works in this sort of half proscenium/ half 360 immersion setting.
spoiler(?)- there's only one completely new song- Dust to Ashes, for Pierre after the duel in the first act. Oh god, it's beautiful, and fits perfectly. I want it recorded now. There's a few lyric changes here and there, the start of "Sunday morning" is different now too. Also "balaga" has an extended dance break and a toast from Pierre.
Weird note- most of the audience was really into the whole experience. But there was a large amount who seemed to just despise it/ think it was too weird. The woman next to me literally didn't know what to do with the pierogi she got at the start, and when she got handed a letter during the top of act two (which was one of my favorite experience at kazino- seeing what crazy messages the ensemble was going to give out that night), she handed it off to me as if she didn't know what to do with it. Bunches of audience members seated in the first row of bar seating would get pissy during any of the moments their view was slightly obscured, and the guy who was tasked with handing the letter to Natasha in the top of act two flat out refused to get up from his chair, and for a second almost didn't give up the letter.
maybe it's just a Boston thing, but the arrogance of some of these people was just ridiculously rude and uncalled for.
