If you are studying a play that has only recently been produced, there may not be much scholarly work yet published on it. In this situation what you need to do is find the most credible sources of information available to you. Theatre reviews are a great place to start: the New York Times, the Wall Street Journal, the Los Angeles Times, the Guardian (London) are all newspapers that publish credible and (hopefully!) well researched reviews of recent plays. In addition, journals like Theatre Journal will often publish extended and intelligent analyses of the plays they cover. Google can be helpful as a way to locate these reviews as well (not as a resource in and of itself!).
Last - but in this case not least - is YouTube. The usefulness of YouTube for this kind of current research is that interviews with the playwright, director and actors are often included in promotional videos to publicize the production. First-hand information from the creators of works is not to be underestimated; remember, however, to supplement this kind of material with secondary sources that deal with the historical, political, or cultural context of the play.
