Find meaning in the music you listen to. Get in the artist head... Ask why they did this or that here or there. Ask yourself why you identify with a piece of music or a performance. then explore that. In the classic Parliament Funkadelic joint "Maggot Brain" with vocals (get it on the P-Funk All-Stars Live At The Beverly Theater with Dennis on drums)George Clinton tells us "Think, it ain't illegal yet...". This statement is never more through than now. All to often we go through the motions without thinking... without asking real questions of ourselves. Music lacks integrity cause we are lying to ourselves first.
When, the discussion of ones sound (voice) comes up we talk about things that really have less to do with our musical sound. Cadence (phrasing, pace), tone, breath, pulse, mental state have more to do with it than we give credence. When negotiators, spys, intelligence officers, Pastors, counselors, etc listen to someones voice it tells the truth of the persons path. It is not the words being said but the way the words are said. Truth makes music, even when it is not your story.
