All Platinum and its subsidiary labels, including Stang, Vibration, Turbo and Astroscope, specialized in soul and R&B music.
The company, with Sylvia helming the creative operations as well as producing or co-producing many releases, racked up a series of R&B and Pop hits during the 70s, despite being only a small independent concern.
The company's mainstay act was the all-male group, The Moments (later Ray, Goodman & Brown) whose first hit at the end of 1968 launched the Stang label, "Not On The Outside" (#13 Billboard R&B, #57 pop).
The group, with a few early personnel changes, stayed with the company for ten years, resulting in over 25 R&B hits and 15 Hot 100 entries.
However, the move was not a success as All Platinum was unable to keep steadily releasing material from Chess's roster of artists.
