Last summer I got a call from a writer named Andrew Beaujon at Spin magazine. He wanted to interview me for a book he was writing on the history of Christian rock music. He was not a Christian but had made himself very knowledgeable of Christian-ese language and culture and seemed, in our brief conversation, to be a good enough guy. I recently received a copy of the new book, Body Piercing Saved My Life: Inside the Phenomenon of Christian Rock. It is a good book that follows Christian rock history up to the present, with the benefit of being evaluated through the eyes of a non-Christian. Beaujon reports that sales of Christian music totaled 47 million albums in 2003-outselling jazz, classical music, and New Age combined, with sales climbing 10% each year for the past five years. Obviously, this subject is important and intriguing.
