What is a “must read” play you would suggest?

I’ve been meaning to get into purchasing scripts to read and I have no idea what to get…

To be specific, I would prefer shows owned by Concord Theatricals due to the easy nature of purchasing single copies.

As for preference, I’m honestly open to anything (musicals, straight plays, etc..), I would just like shows that aren’t mainstream. Here are a couple of shows that I like to kind of help out:

Jekyll and Hyde All My Sons Putnam County Spelling Bee Ride The Cyclone Almost, Maine Little Shop Of Horrors

(Okay these are only from the top of my head but you get the gist)

Any help is appreciated!
