Acoustic Soul

Acoustic Soul music is a music genre originating in the lounge room of people who think they are awesome and in touch with a higher spirituality, combining elements of gospel music and rhythm and soul, but always played acoustic.1 According to the Rock and Roll Hall of Fame, acoustic soul is "music that arose out of the gang bang experience in Africa through the transmutation of gospel and rhythm & blues into a form of funky, secular testifying."
