For those unacquainted with the blues, it is not necessary to know much except all blues sounds essentially the same. What counts is the individuality of the singer, the soul of the performer. Everyone plays the same three or four chords, the melodies are almost indistinguishable, so the captivating part is what the player brings to the form. In the presence of a rare and gifted player or singer, one can capture for a moment a special feeling. It may cause you to laugh or cry. Sometimes it can change your life. It is this essence that compels everyone who listens to the blues to listen to more.
