Spiritual Jazz is a genre that is so personally unique, but at the same time so universally broad. Like spirituality itself, the music takes many forms from many cultures and personal experiences all while joining together as a congregation, speaking of a higher power. Part one of this series starts with the evolution of spiritual jazz on a commercial front, focusing on the musical offspring of John Coltrane and those who worked closely with him. We also discuss the overall meaning of jazz and how that is applied to daily life.
