If you have not yet seen the show and you are able to do so, see it. Drink it in. It is the strongest social commentary on repression of ALL people, not just teens, I have seen in a long time. Read the script. Discuss with your friends. It is as multifaceted as a diamond. It is the anthem to an era.
As a vocalist, I own the vocal selections to about 15 musicals I have enjoyed. Every time I get the same watered down vocal lines, removed harmonies, gross accompaniments and rhythms that seem to have been transcribed by a first year music theory student. Not so with this book. This book has the significant harmonies that can be heard on the soundtrack. It is truly a masterful transcription of a difficult score. All the songs you could want are there.
The best vocal selections I have in my possession.
