Contrary to what its title suggests, The O'Jays in Philadelphia isn't a live album. Rather, the title of this studio date refers to the beginning of their association with Philly's R&B scene and producers/songwriters Kenny Gamble & Leon Huff. What they didn't know in 1969 was just how long and fruitful that association would end up being. This album wasn't the major hit that Back Stabbers would be, but not for lack of strong material. From "One Night Affair" to "Let Me in Your World," this superb album is quintessential Philly soul. While Eddie Levert's gospel-influenced belting is as gritty as anything that came from Stax Records, the production is as notably sleek. A few years later, Gamble & Huff would produce a longer, heavily syncopated version of "Affair" for Jerry Butler that some soul historians exalt as the first disco single.
