Mary Mary is an American contemporary gospel duo, consisting of sisters Erica Atkins-Campbell and Trecina “Tina” Atkins-Campbell. The duo are often credited along with Kirk Franklin for broadening the fan base of urban contemporary gospel in the 2000s by introducing elements of soul music, hip hop, funk and jazz. Mary Mary broke onto the music scene with their popular song “Shackles (Praise You)"—which is considered one of the pioneering songs of urban contemporary gospel music. "Shackles” peaked at #28 on the Billboard Hot 100 Chart, and became a worldwide crossover hit, peaking in the top 10 or higher in the UK, Netherlands, New Zealand, Brazil, and Norway, among others.

The group’s name, as stated in an interview is inspired by the two famous Marys from the Bible; Mary, the mother of Jesus Christ, and Mary Magdalene, and is intended to represent the idea that no matter where you come from or what your reputation is, your life can still be greatly affected by Jesus.
