I have seen several incarnations and look forward to seeing this staging.
It's not really a musical OR. A play, it is, as stated earlier, something different.. A puppetry perfomance piece, perhaps... More akin to seeing a ballet.
It really is a beautiful production, very rich, very detailed and elaborate yet quite simple. I can see where certain people who like to be spoon fed and have things spelled out may find it alienating, as it does require you to dial in and engage yourself. The musical scoring is beautiful and the sound of the show is subtle and rich, with all sound effects being manually created by the actors. Yes, there is an opening monologue to establish time, place and circumstance, but then you have to dial in and follow.
I agree with the earlier post that says the sounds of the birds are still vivid. They are absolutely fresh in my mind.
The three best moments coup de theatre moments for me, no spoilers, have to be the appearance of the Kalidah (I gasped and applauded that), seeing Nick Chopper become the Tin Woodsman one limb at a time, and particularly the 'reveal' with the cyclone that carries Dorothy to Oz.
James Ortiz's work on this production is absolutely fantastic and a wonderful exploration of a little retold chapter in THE WONDERFUL WIZARD OF OZ.
