"I can't do pieces I only admire technically. I have to feel some direct contact with them"

This quote by Michael Tilson Thomas talks to the value of emotion in music. He is saying that he can not appreciate a piece of music unless he feels a direct connection to it. This connection is likely psychological, as music is typically used to stimulate certain sensations. He is stating that technical skill alone is not enough to value a piece of music. It should also have a psychological resonance with the listener. This is why some pieces of music can be technically excellent, however still stop working to move the listener. It is only when the technical skill is combined with an emotional connection that a piece of music can truly be valued.
