Don't remember how I got to him the other day, but found this incredible medley from Les Miserables by Nick Pitera. For his day job he's an animator at Pixar, which is cool enough, but he's been online making awesome music before he landed that gig. His vocal range is incredible, which you'll see amply demonstrated in this video.
Still haven't seen the film (maybe next weekend), but I did see the play years ago when I was most likely too young--early teens--to really get it. I do remember liking the music, and being amazed by the performances, but that's really all. The Master of the House segment is probably my favorite.
