With sweeping violins and scratch guitar, soul music is the product of the vulnerable expression of the black experience. Romance, hardship, heartache, and deep desire are the staples of soul. Hot soul, featured in the 1970’s, laid the foundation for it later in the 1980’s. In addition, influences of funk and disco are also found in the genre. An exemplary band for the early stages of soul was the O’Jays. R&B, Philadelphia soul, progressive soul, and contemporary soul are the different labels attributed to the band. Spanning over a dozen albums throughout the decades, nearly all of the O’Jays discography feature introductory orchestral strings and horns, repetitious wah-wah guitar, and themes of love and pain.
