Louisiana born Bobby Rush invented, and personifies the blues style known as Folk-Funk. His brand of music blended the Chicago blues, southern soul and finger plucking funk into some scandalously enjoyable 45s. "Mary Jane" is the 1971 flip to his breakthrough hit "Chicken Heads". File under stoner mix and enjoy.
Bobby Rush, nearly forty years later, performing "Chicken Heads". You'll notice that his soul-dripping jerry curls, along with his live performances, haven't lost any of their shine.
