I do think it is worth getting. Many great singers on it! I would have to agree, I have yet to fall in love with it. I am not sure how much it helps but it has been a book and a movie as well, so maybe finding synopsi (?) on those would be easier. Not sure how much different they are from one and an other.
(Martha Graham from a letter to Agnes de Mille) "There is a vitality, a life force, a quickening That is translated through you into action, And because there is only one of you in all time, This expression is unique. If you block it, It will never exist through any other medium And be lost. The world will never have it. It is not your business to determine how good it is, Nor how valuable it is, Nor how it compares with other expressions. It is your business to keep it yours, clearly and directly, To keep the channel open. You do not even have to believe in yourself or your work. You have to keep open and aware Directly to the urges that motivate you. Keep the channel open. No artist is pleased. There is no satisfaction whatever at any time. There is only a queer, divine dissatisfaction, A blessed unrest that keeps us marching And makes us more alive than others."
