New book: "The Spiritual Significance of Music"

Just came out and features brief interviews with tons of secular and Christian artists about the spirituality of music. Some transcripts of the interviews available here:

There is an interview with my band TEMPLE OF BLOOD in the Christian edition of the book:

Lots of interesting artists, but I would have prefered a bit longer, in depth interviews.

Is this just an online thing or actually a book?

It's a book (actually two books).

Ok thanks.
