Philly soul: the sound of Philadelphia

In the early 1970s Philadelphia produced the smoothest, most orchestral soul in America, played over a rhythm section tight enough to fill dance floors. Its musicians helped set up disco.

Who built it

Songwriters and producers Kenny Gamble and Leon Huff founded Philadelphia International Records in 1971. Alongside producer and arranger Thom Bell, who worked with the Stylistics and the Spinners, they defined the city’s sound. Much of it was recorded at Sigma Sound Studios with a pool of session musicians who also released records as MFSB.

What to listen for

Strings and horns, fully arranged. Philly records use orchestral sweep the way Motown used tambourine: as a signature.
A driving rhythm section. Drummer Earl Young’s steady hi-hat and kick patterns are often pointed to as a foundation of disco drumming.
Big voices and falsetto. From Eddie Levert’s grit in the O’Jays to Russell Thompkins Jr.’s high tenor in the Stylistics.
Message songs. Gamble & Huff wrote about money, betrayal and community as well as love: “For the Love of Money,” “Wake Up Everybody.”

MFSB’s “TSOP (The Sound of Philadelphia),” the theme for the TV show Soul Train, became a No. 1 hit in 1974 and is the simplest summary of the style.

Where it leads

Philly’s rhythm section fed directly into disco; its ballads fed quiet storm radio; and Teddy Pendergrass became one of the major solo R&B voices of the late 1970s. Back in the funk timeline, see 1970s funk.

Hear the strings: the layered arrangements on these records are where cheap Bluetooth speakers struggle most. A pair of proper stereo speakers, placed apart, makes a real difference. See powered speakers for a small listening room.
