Famed for recording the main theme to 70s music television staple, Soul Train, as well as providing the backbone to Philadelphia International's era-defining Philly Sound through other label mates' respective releases, instrumental group MFSB (Mother Father Sister Brother) also maintained a steady output of their own throughout the decade. With no less than 30 members accounted for within their back catalogue, MFSB's very name gives credence to the grassroots appeal of the Philly Sound which established the framework in which disco would emerge and once again redefine R&B in the 70s. MFSB's third LP UNIVERSAL LOVE (US #44/R&B #2), released in 1975 on Philadelphia International, continued to establish MFSB as a mainstay within the Philly Sound era with the help of pioneers Kenneth Gamble and Leon Huff and other regular fixtures within Philadelphia International's creative team.
