Before Casting Crowns was created they were known as New Life Rookies which split into two bands, one being Casting Crowns and the other a smaller band South Avenue.
From Wikipedia:Casting Crowns is a Grammy Award and Dove Award winning Christian rock band. Casting Crowns was started in 1999 by youth pastor Mark Hall at First Baptist Church in Downtown Daytona Beach, Florida as part of a youth group. He now serves as a lead vocalist. Later they moved to McDonough, Georgia and more members joined creating the band now known as Casting Crowns. Some members of the band currently work as ministers for Eagles Landing First Baptist Church in McDonough, Georgia.
