Gordon looks at changes in worship from the fresh viewpoint of a Media Ecology perspective.
Changes in music have changed the way we think, and the way we worship - or are even able to worship.
The musical culture we are immersed in has altered our ability to understand other genres of music - so much so that we find them strangely unhelpful.
This means that worship has become a conflict area, rather than a source of unity.
Gordon not only shows the problems, he also provides solutions - it's important, because how we sing affects how we live.
