This is a generally great book of scores from this awesome musical, however its downfall is that some of the scores have been changed from the origional stage pieces you know and love, to adapted pieces for the solo voice, that work around where scripting would have been in the show or where there would have been chorus's or duets. I find that the adapted "Defying Gravity" in particular, does not quite meet expectations for what was a spectacular showstopper on the stage. It is a good buy if you love to sing, play guitar or piano and above all, love "Wicked".
