When Sister Sledge recorded their debut album, Circle of Love, in 1974, all four members of the group were still in their teens -- Debbie Sledge, the oldest member, was 19, while the youngest, Kathy, was only 15.

However, there's nothing bubblegum about Circle of Love.

If Sister Sledge sounded like a female equivalent of the early Jackson 5 on 1973's "Mama Never Told Me," this vinyl LP found the Philadelphians sounding more like a younger version of the Three Degrees (who were also from Philly).

This LP had a gem of a single in the haunting "Love, Don't You Go Through No Changes on Me," which wasn't huge but did reach number 31 on the R&B charts.

The rest of the album isn't that strong, nor is it in a class with Sister Sledge's late-'70s/early-'80s work with Chic and Narada Michael Walden.

Nonetheless, it's a decent, if uneven, collection of Philly soul, and the siblings handle themselves well on material ranging from the Gamble & Huff-minded "Pain Reliever" and the charming "Cross My Heart" to the Thom Bell/Linda Creed ballad "Give in to Love." Circle of Love isn't among Sister Sledge's essential albums, but it has historic value and deserves attention from fans.
