The interesting thing is that the older crowd will definitely capitulate more towards a younger sound, musically speaking, but the younger crowd won't go "older." This is just speaking stylistically.
But, more importantly, the difference in world view is much more prominant in the actual song content. There are songs that I can't actually do at either service because of the lyric approach, not musical style so much. Most songs, I have found, can be musically reinterpreted to fit a specific group.
With our Canvas crowd there is a desire to explore different facets of worship. Songs that are darker in tone are more acceptable. The desire to worship God through the idea of our brokeness is huge. And this speaks to the high value of at least perceived authenticity.
Whereas the Boomer group prefers the happy kind of "victorious," up worship style. They definitely resist exploring the darker or edgier ideas. I don't think it is an inauthentic approach as much as it is a desire to relate to God as having overcomed or temporarily put aside our brokeness; rising above it, if you will.
The boomers would accuse the busters of wallowing in their baggage. Where the busters would accuse the boomers of candy coating the experience and putting on a fake smile.
Some of these differences in world view were exacerbated for me when I introduced a new song I had just written to both crowds.
Tune in tomorrow!
