The album was released in late 1975 on the Philadelphia International Records label. Recorded at Sigma Sound Studios in Philadelphia, and produced by Kenny Gamble and Leon Huff, Family Reunion includes the enduring classic "I Love Music" and "Livin' for the Weekend", both of which topped the R&B singles chart, and placed at #5 and #20 respectively on the pop chart. The ballad "Stairway to Heaven", originally issued as the B-side to "Livin' for the Weekend", has also gone on to become a staple of quiet storm programming. While the title track did not chart, it still garnered airplay, as the lyrics (as well as the album artwork) focused on the importance of the family structure especially at gatherings.
Family Reunion became the group's third consecutive R&B chart-topping album, and its #7 peak on the pop chart was their highest placing on this chart at the time (1978's So Full of Love would peak one place higher). Family Reunion was awarded a Platinum Album for RIAA Certification of over one million copies sold.
