That's not to say there's no value in reading a play's manuscript, or examining a piece of sheet music for yourself. Certainly one can gain greater appreciation for a director's vision if you've read the play yourself. Just as one will appreciate a painting more if you're familiar with the subject of that painting (thus the constant research to identify who exactly Mona Lisa was and her relationship to DaVinci. And The Last Supper surely would not carry the same weight if it were just Twelve Dudes Having Dinner).
