Acappella is an all-male Contemporary Christian vocal group founded in 1982 by Keith Lancaster, who has variously played the role of singer, songwriter and producer throughout the group's history. Believing in the awesome versatility and flexibility of the human voice, Acappella can fill a large concert hall with beautiful, intricate music without instrumental accompaniment.
Acappella's current lineup is Robin Brannon, Zac George, Anthony Lancaster (son of founding member Keith Lancaster), Wes McKinzie and Zach Wilson. Past members have included Lancaster, Duane Adams, Allen Brantley, Rodney Britt, Wayburn Dean, Nic Dunbar, Gary Evans, Robert Guy, Jordan House, Ken McAlpin, Gary Miller, Gary Moyers, Matt Nunnally, George Pendergrass, Steve Reischl, Sean Samuel, Steve Maxwell, Kevin Schaffer, Rob Smith, JJ Blevins, and Barry Wilson.
