Music can evoke a trance through rhythmic induction. Repetition of a beat affects theta brain waves which can lead to an altered state of consciousness. The head bobbing that everyone in unison does at concerts, the feeling of connection with those around you. These are ancient phenomenon brought to experience through auditory driving. For thousands of years people have felt what you are describing - induced from chanting, drums, etc.. I believe the word you're looking for is trance.
