Musicals are not just a Broadway thing. In fact, if you want to get on the ground floor of the hottest new musicals, you should go off Broadway. This is where the newest, weirdest, most-adventurous musicals come from. Hamilton, Hadestown, Rent, and Spring Awakening are just some beloved musicals that had buzzy runs off Broadway before debuting to a wider audience on Broadway. So if you want to be the first one to see the musical that everyone will be talking about a year from now, see an Off-Broadway show.
