No two people hear the same piece of music exactly the same. Age, listening experience, different cultural backgrounds,etc. all influence how we hear a particular piece of music; for example, a person brought up in India, listening to Indian music, upon hearing Ravi Shankar playing a raga would hear a very different piece of music than somebody from Texas who was brought up on country music. This is just a - rather extreme - example of why it can be wrong to assume that if a performer doesn't communicate with a listener, then it's the performers fault.
