The sound arrives before the singer. “Back Stabbers” (1972) opens on a piano figure rolling up out of silence. The title “sounds like something eerie,” Leon Huff said of the song he built that figure for, “so that roll was like something horrible, because that’s what back stabbers are.” Then strings, then congas, and only then three voices from Canton, Ohio, harmonizing a warning about false friends over a beat built for dancing.1 A rhythm date in that room could run, by its engineer’s count, to “54 to 60 people—almost a symphony orchestra,” and the engineer, Joe Tarsia, called what the room produced “Black music in a tuxedo.”2
Philadelphia soul is what Kenny Gamble, Huff, and Thom Bell built in that room between the mid-1960s and the early 1980s: gospel-schooled voices and doo-wop harmony set inside a working orchestra, strings voiced low under the vocal, French horns where the saxophones would go, a rhythm section that never stopped swinging, and, at the center, the conviction that a dance record could carry a sermon. Its company, Philadelphia International, ran second only to Motown among Black-owned music businesses, and the beat that conquered the following decade was invented by its house musicians.3
The elevator
The founding meeting has an official version and a true one, and Gamble tells the difference himself. “The official story has us meeting in the band, the Romeos,” he said, the group he sang with on weekends. “But actually, Huff and I worked for different production companies in the Schubert Building, which was Philly’s Brill Building, a hotbed of local songwriters. He worked on the second floor, me on the sixth and we met on the elevator one day.” Huff remembered the same ride from his side: “I had never seen Gamble, and he had never seen me.”4 The city they were riding through had a hit factory already — Cameo-Parkway, the label whose Chubby Checker singles ran on American Bandstand exposure — but its staff was, in one historian’s summary, “predominantly white,” and it largely ignored soul music until 1964. That year the British Invasion began starving its teen-idol business, and the label asked a young Black staffer named Thom Bell to form a rhythm section and try producing some.5 The apprentice generation grew up in that building’s shadow and inside it: Gamble was discovered at seventeen by the producer Jerry Ross (“Before there was a Gamble & Huff, there was Gamble & Ross!”), who recorded Gamble and Bell, teenage friends who had sung together at record hops, as a doo-wop duo called Kenny and Tommy.6
The independent years taught the partners a business. Their first national hit as writer-producers, the Soul Survivors’ “Expressway to Your Heart” (1967), reached No. 4. Their own Gamble label put the Intruders’ “Cowboys to Girls” at No. 1 R&B with a gold record by May 1968. And Neptune Records, their Chess-distributed second label, signed the O’Jays, Billy Paul, and the Three Degrees before it folded inside two years — its label art already reading “The Sound of Philadelphia.”7 Bell’s line ran parallel. He had conducted Chubby Checker’s road band at nineteen; by 1968 he was producing the Delfonics on Philly Groove, and “La-La (Means I Love You)” took William Hart’s falsetto to No. 4 and set the template for the genre’s romantic wing. “People used to have contests to see who could sing the highest,” Gamble said of Hart, “and Poogie was right there with the best of them.”8 The infrastructure arrived the same year: Tarsia, Cameo-Parkway’s former chief engineer, took a $40,000 loan and opened Sigma Sound Studios in August 1968, and Gamble, Huff, and the Delfonics were among the clients on its first day of business.9
What the apprenticeship still lacked was proof at national scale, and it came through other people’s stars. Jerry Butler, Mercury’s “Iceman,” gave Gamble and Huff The Ice Man Cometh (1968) and its million-selling No. 4 hit “Only the Strong Survive”; AllMusic later called the album “the first time R&B production techniques reached a level of maturity.”10 Atlantic sent Dusty Springfield to the same team for the Philadelphia sessions that became A Brand New Me, and sent Wilson Pickett to Sigma, where a studio jam turned into “Engine Number 9” and the players on the date — Earl Young, Ronnie Baker, Norman Harris, Bobby Eli, Bell on organ — were the house band of the next decade in embryo.11
The company
Philadelphia International was founded in 1971 on CBS money and Philadelphia terms. Clive Davis, looking for a door into the Black music market, advanced $75,000 for singles and another $25,000 for albums. Gamble and Huff took the distribution, kept their masters, and refused to hand over the rights to their earlier records. Davis signed them anyway.12 Gamble never pretended the model was original. “Motown, in my view, was the greatest record company that ever existed,” he said. “They were the blueprint for Philly International.”13 Like Gordy, the founders set up competing teams of staff writers — McFadden & Whitehead, Bunny Sigler, Victor Carstarphen, Cary Gilbert — and ran artists through forty or fifty auditioned songs per album. The founders themselves never left the writers’ room: the company existed so that Gamble and Huff could keep making records.14
The instrument the system played was MFSB, the pool of thirty-plus Sigma session musicians formalized in 1971: the Romeos’ old rhythm section at the core, “a group of horns they saw playing a local theater, and a string section composed of retirees from the Philadelphia Orchestra.”15 Tarsia recorded them the way they wanted to sit — “They wanted to feel each other. They wanted to be close. Ronnie Baker, the bass player and Earl Young, the drummer, wanted to sit right next to each other” — and adjusted his engineering to his clients’ two ears: “Kenny loved the piano, Leon loved the bass.”16 In 1973 the partners bought the building at 309 South Broad Street for their headquarters, the very building Cameo-Parkway had occupied. “Cameo Parkway, which had Chubby Checker, Bobby Rydell and Dee Dee Sharp, was a major record label and cultural force at the time,” Huff said, “and our offices are the same ones they had.”17 The system was confident enough that its signature hit needed no singer at all: “TSOP (The Sound of Philadelphia)” (1974), written as the Soul Train theme, sent the house orchestra to the top of the pop chart under its own name, titled with initials because Don Cornelius refused to let the show’s name appear on the record, a decision he reportedly came to call “one of the biggest mistakes of his career.”18
The message
The label’s message years belong first to the O’Jays, a group that had spent fourteen years and dozens of singles without a Top 40 hit and was close to quitting when Gamble and Huff signed them. “Back Stabbers” went to No. 3 in the fall of 1972; “Love Train” entered the Top 40 on January 27, 1973 — the day the Paris Peace Accords were signed — and reached No. 1 in March, a song whose vision of unity named nations the way gospel names the saved.19 The sermon deepened on Ship Ahoy (1973), whose title track spends nearly two and a half of its nine and a half minutes on creaking timbers, thunder, and a cracking whip before a word is sung: the Middle Passage as album centerpiece. Gamble later stood at the door of a slave-trade fort in Ghana and described what the song was for: “We stood in the Door Of No Return that led you right to the slave ship and that was it for you, you were done… finished with your family, your children, your wife.”20 The same album carried “For the Love of Money”, whose bass line earned session player Anthony Jackson a writing credit: he ran his bass through a wah-wah pedal, Tarsia recorded the part twice, “once normally and once phased,” then flipped the tape to print echo in reverse ahead of the vocals, and Gamble, at the final mix, reached over and stabbed the echo button on the opening riff himself.21
The message had a price list, and Billy Paul paid it. “Me and Mrs. Jones” (1972), a story Gamble said he watched unfold from a café table — the same man, the same young woman, day after day — held No. 1 for three weeks and won the Grammy. For the follow-up, Gamble chose “Am I Black Enough for You?”, and Paul begged him not to. “The only song I told Gamble not to release was called ‘Am I Black Enough for You?’ which I thought would turn off a lot of people. Gamble released it anyway.” Pop radio, in one journalist’s summary, deemed the record militant and blackballed the singer; the single stalled at No. 79, and Paul said later, “the song failed, and I never got back up to where I had been.” His own explanation of Gamble’s choice is the genre’s creed stated from the receiving end: “I guess he thought it was more important to use my fame to get the word out than to help my career.”22
Harold Melvin & the Blue Notes carried the label’s biggest voice. Teddy Pendergrass had joined as the backing band’s drummer in 1970 and was promoted to lead the same year; Robert Christgau heard “just about the most powerful voice ever to hit soul music” in him, and “If You Don’t Know Me by Now” (1972) took it to No. 3.23 The group’s up-tempo records kept detonating elsewhere: “The Love I Lost” (1973) left its session faster than it was written and became, by the usual accounting, disco’s first record,24 and “Bad Luck” (1975) sat on Billboard’s disco chart at No. 1 for eleven straight weeks, driven by a hi-hat mixed so loud it could not be quieted, an accident A House on Fire credits with helping shape disco’s approach to percussion.25 “Wake Up Everybody” (1975) was Pendergrass’s farewell to the group. “That song is self-explanatory,” Gamble said of it, “because it is the way the world is right now. People living in darkness.” The billing fight behind the split had been running for a year: Melvin controlled the money, audiences kept mistaking the singer for the man in the group’s name, and Pendergrass quit in 1976 to sign with the label solo.26 One measure of what the catalog was worth traveled to Detroit: “Don’t Leave Me This Way,” an album cut on Wake Up Everybody, became a No. 1 single in 1977 for Thelma Houston — on Motown.27
The Bell line
Bell heard his instrument in a voice. Auditioning the Stylistics for Avco, he was unimpressed with the group and persuaded by Russell Thompkins Jr.’s high, nasal tenor: “With Russell Thompkins, I heard an English horn, a bassoon, I heard the double reeds.” He built the records around that discovery, and around a private orchestration creed: “French horns were very prevalent in everything I did, and the reason why I did everything with French horns was because saxophones bother me!” The strings stayed deliberately underneath the voice. “I voiced it low. I always voiced things low because you want to hear the strings, but you don’t want ‘The Philadelphia Strings Starring The Stylistics!‘”28 His writing partner was the lyricist Linda Creed; “We were like brother and sister,” he said. Together they wrote the run that made the group: “You Are Everything”, “Betcha by Golly, Wow” at No. 3, “You Make Me Feel Brand New” at No. 2. Every single Bell produced for the Stylistics reached the R&B Top Ten. Creed’s part of the songbook outlived her: she died of breast cancer in April 1986, at thirty-seven, five weeks before “The Greatest Love of All,” her lyric with Michael Masser, reached No. 1 in Whitney Houston’s recording.29
The Spinners were the Detroit group Philadelphia perfected. Stalled at Motown, they moved to Atlantic in 1972 at Aretha Franklin’s suggestion; their lead singer stayed behind under contract and sent his cousin, Philippé Wynne, in his place. Bell produced them at Sigma with MFSB underneath, and the results ran for five years: “I’ll Be Around” — a B-side that radio flipped into five weeks atop the R&B chart — “Could It Be I’m Falling in Love”, “The Rubberband Man” at No. 2, and “Then Came You” (1974), the duet with Dionne Warwick that gave her the first No. 1 of her career.30 The industry named what it was watching: when the Recording Academy created the Producer of the Year award, at the 1975 ceremony, the first name engraved on it was Thom Bell.31
The sermon and the bill
Gamble’s convictions were the company’s editorial line, and he traced them to James Brown and Curtis Mayfield: “I think my early years of listening to the radio, and listening to people like James Brown and Curtis Mayfield, inspired me to write songs with social meaning.” The Philadelphia DJ Georgie Woods drew the distinction that kept the records playable: “Gamble and Huff never preached. They were committed to a single purpose: the well being and welfare of their people.”32 By mid-decade the conviction had a title track: the O’Jays’ 1976 album Message in the Music. Gamble himself, his marriage failing as the label’s troubles began, converted to Islam in those years, taking the name Luqman Abdul Haqq.33
The troubles had arrived on June 24, 1975, when a federal payola investigation called Project Sound indicted nineteen people and six corporations, Gamble and Huff among them, on accusations of moving roughly $40,000 in cash, airline tickets, and clothing to radio DJs. Huff’s charges were dropped, and Gamble plea-bargained and paid a fine. The company’s momentum absorbed a wound that A House on Fire weighs as one cause of the fall among several — the rivals, the economy, and the audience’s drift did the rest.34 The genre’s last superstar run belonged to Pendergrass, whose five consecutive platinum albums and women-only concerts made him the label’s late-decade engine — until March 18, 1982, when his Rolls-Royce left Lincoln Drive and hit two trees. “We were on Lincoln Drive when the brakes went out,” his passenger Tenika Watson remembered. He was paralyzed from the chest down at thirty-one.35 The CBS deal ended mid-decade, MFSB played its last sessions in 1985, and the era that had announced itself by name was over within a working generation of the announcement.36
What was left
The afterlife split between the founders’ city and everyone else’s records. Gamble turned his royalties toward South Philadelphia — “during the seventies I started to buy many of the abandoned houses and vacant lots in that neighborhood,” he said, a project that grew into the Universal Companies development organization; asked why, he reached for the catalog: “We had a song a long time ago called ‘Clean Up the Ghetto.‘”37 In 2008 the Rock and Roll Hall of Fame made Gamble and Huff the first recipients of its Ahmet Ertegun Award, and the man who presented the induction was Jerry Butler — the Iceman, whose Mercury sessions had proven the sound before the company existed.38 The music’s genetic line runs through the records that came after it: the four-on-the-floor Earl Young built inside these sessions became disco, and through disco everything that dances in its wake.
The address fared worse than the sound. Detroit’s Hitsville and Memphis’s Stax stand as museums. 309 South Broad Street, damaged by an arsonist’s fire in 2010, was demolished in 2015 for a condominium tower, and Philadelphia has no museum for the company that carried its name around the world.39 What survives needs no building: the sound still arrives before the singer.
