Sister duo Mary Mary are gearing up for the March 29 release of their sixth album, titled Something Big.

The project, produced by Warryn Campbell, features the hit single “Walking,” which has already climbed to the #6 position on radio this week. The single can be purchased digitally now, or buy it at your local WalMart and receive a bonus track with it– “Something Bigger.”

The ladies will also be on BET’s Celebration of Gospel this Sunday, January 30 at 8pm ET, performing “Something Big,” the catchy call and response anthem and title track from their upcoming project.
