The richly orchestrated, string-laden Sound Of Philadelphia that emerged from Sigma Sound Studios in the early seventies, courtesy of the O Jays, Stylistics, Three Degrees and the Intruders, was actually born a decade earlier in the heart and soul of Harthon Productions and its pioneers John Harvey Stiles, Luther Anthony Randolph and Weldon Arthur McDougal III. This collectors singles perfectly capture the true essence of the unique Harthon sound that has fueled the Northern Soul scene for over 40 years.
