The emotional power of music

The St Paul's Theological Centre, part of Holy Trinity Brompton, have just released a sound recording of their annual lecture. Given by James Steven, it addresses the emotional power of music in worship, and whether this is something to be feared. I've yet to listen to it, but it is another example of the debates going on within the contemporary Christian music scene, and, I think, a sign of increased self-awareness within the scene as a whole (difficult to imagine the same debate happening amongst evangelicals in 1970, say).
