Here is an interview from a group in the UK called Fresh Expressions. I really appreciate the heart of this article as they talk about imagining a way to worship that is creative, centered around the particular culture of your community, and sustainable. Some good reminders, so that we're not taking on change just for the sake of changing.
Along with this article, there are some other resource tabs on this website that might be helpful to check out.
