My wife finally just bought me the Bluray of the 25th Anniversary Concert after I kept refusing to delete it off the DVR. Shame, because I'm much more likely to see it on the DVR screen and watch a song or two than to have to go to the trouble of finding the disc and popping it in.
What are your thoughts on 10th Anniversary vs. 25th? I honestly didn't mind Nick Jonas as much as some people, and was very pleased w/ Alfie Boe and Norm Lewis as Valjean and Javert. I'd still probably give an edge to the 10th though (where I love Lea Solonga's rendition of On My Own).
I think a combination of the sweeping historical scope, the core themes that run throughout, and the fact that there are so many 'main' characters who have nice solo pieces (as opposed to something like Phantom - which I also like - where it's all Phantom and Christine [and a little Raoul] and the rest ensembles pieces) which really gives a nice variety.
