Just a quick note to point you to this great interview on BBC Ulster with RiAH contributor and former blogmeister Randall Stephens about his forthcoming work The Devil's Music: Christianity and the Rock Since the 1950s (which Harvard U. Press will publish sometime down the road a bit). The book "will delve into the sometimes productive, sometimes tumultuous relationship between so-callsed sacred and profane music from the days when Elvis first made it bit to the modern era of the multi-million dollar Christian music industry. The interview nicely intersperses the music with the Randall interview segments.
The link takes you to a post from the American Studies program at Northumbria University (in Newcastle, England) about the work and the interview.
