There is no single sound that defines the 70s but there is no doubt that Philly Soul, or the Sound of Philadelphia, is an essential element. The O'Jays, The Spinners, Three Degrees, Harold Melvin and the Blue Notes, and Billy Paul are just some of the artists that created silky, lush soul records under the direction of "The Mighty Three": Thom Bell, Kenny Gamble, and Leon Huff. With a distribution deal from Clive Davis at CBS Records, Gamble and Huff were not only the McCartney and Lennon of the 70s, they created Philadelphia's Motown. Their brand of soul, or "funk dressed in a tuxedo" was not just dressed up R&B, but also told stories and spoke to social issues that were part of the fabric of the 70s.
