Stephen, Jr., Sierra and Shanté Leslie grew up in a Washington, D.C. household where appreciation for music was inherent and church was woven into their lives. Their grandfather, Bishop John T. Leslie, Jr., pastored The Church of Jesus Christ in Southeast, D.C., where their mom was on the praise and worship team and their uncle, Professor Wilbur Belton, Jr., was minister of music. Additionally, their dad is an accomplished musician who was a mainstay in the jam sessions of good friend and Trilogy producer Dana Sorey, Tye Tribbett and members of one of the baddest bands in Gospel music: SoundCheck. With this musical saturation, it comes as no surprise that the Leslie kids would form their own group. First introduced to the public as STL3, the group garnered a Stellar Award nomination for its debut project.
