The sisters of R&B singer Jesse Powell, urban duo Trina and Tamara hailed from Gary, IN. The Powells relocated to Philadelphia in 1983, and there all four siblings -- as well as their mother Emerald -- performed in the family group Sheer Joy. When Jesse headed for Los Angeles in 1990, Trina and Tamara followed, and established themselves as session vocalists. As members of the group Somethin' for the People, the sisters also scored a hit in 1997 with "My Love Is the Shhh.." Signing to Columbia, the duo released their self-titled debut album in 1999. ~ Jason Ankeny
