The Godfather.
"Soul Brother Number One," "The Godfather of Soul," "The Hardest Working Man in Show Business," "Mr. Dynamite" -- James Brown had many sobriquets. He turned R&B into Soul and Soul into Funk. He could be listed as the most important artist in any of those genres. Perhaps the most influential American music artist of the latter half of the 20th century.
At the age of 16, Brown was arrested for stealing a car and sentenced to three years in prison. He met singer Bobby Byrd while incarcerated and, with the help of Byrd's family, he gained parole. The two formed a gospel group and later changed their focus to Rhythm and Blues.
