Michial Farmer moderates a discussion with David Grubbs and Nathan Gilmour about the history, character, and aims of Christian rock and its later Contemporary Christian Music counterparts. Along the way we talk about the history of musical production, and David sees his normal continuity and Nathan insists on historical difference. Among the musicians, historical phenomena, and texts we discuss are Larry Norman, the Jesus Movement, Second Chapter of Acts, Steve Taylor, Audio Adrenaline, Mercy Me, and niche marketing.
