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.

Their debut album Thankful (2000) was certified Platinum. The duo has released three Gold albums: Incredible (2002), and Mary Mary (2005), which all charted #1 on the Billboard Top Gospel Albums.

Valley Low CD. At the same time, Mary Mary as a musical entity took shape. Mary Mary together with Bebe & Cece Winans featuring the West Angeles Choir performed at The Tonight Show With Jay Leno
