What do you think? I like it...I'll have to listen to it several more times to decide how much I like it, but so far, I like it a lot. 
There are two things I dislike. First, the slo-o-o-o-w tempos. Some parts--some entire songs--drag on like dirges. No wonder this recording went to two discs.
I also don't care for Daniel Evans as Act One George. He has a Scottish accent which get muddied up throughout (especially during the part with the two dogs.) He has a beautiful voice and I think he's fine as Act Two George, but I don't think he carries off Seurat at all. (Is Act One George ever referred to as Seurat? Hmmmm...)
Otherwise, I love Jenna Russell as Dot/Marie. Not as good of a singer as BP, but she acts the roles much better.
I also like the new orchestrations. In fact, I like how this entire recording sounds. I don't know what the technical term is, but it's the "warmest" cast recording I've heard in years. There's a robust, full-bodied sound overall.
And it's a treat to have the entire score included, though I wish not as much of the spoken dialogue was present (a wish I have for all cast recordings in general.)
