Mary Mary is a two-time Grammy award winning Platinum American gospel music duo, consisting of sisters Erica Campbell (born April 29, 1972) and Trecina Campbell (born May 1, 1974). 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.
Their current release, The Sound,again was #1 on the Top Gospel Albums; as well as #7 on the Billboard 200. It has spawned two highly successful singles: Get Up and God In Me. In Spring 2009 God In Me began achieving crossover success (as Shackles had nine years earlier), reaching #5 on the Hot R&B/Hip-Hop Songs, and #1 on the Hot Dance Club Play.Content: http://en.wikipedia.org/wiki/Mary_Mary
