It will cost you a few bucks, but if you want to understand art and "cultural creatives" you should get Tim Keller's message "Christianity and the Creative Age." This is a lecture given for the Redeemer InterArts Fellowship in September 2006. The Redeemer InterArts Fellowship is "for anyone working in (or interested in) the fine or performing arts, design, media, or entertainment."
This lecture is helpful on consumerism, art & artists, the city, creativity and relationships. It's particularly helpful for pastors desiring to encourage a biblical view of the arts and, obviously, artists.
