Here are a few books that you would find inspirartional and thoughtful if your in the arts industries and particularly if your struggling with the whole thing on understanding a theology of the arts or simply trying to get to grips with the art purpose/direction.
These books are by Calvin Seerveld, Emeritus Professor of Theorectical Aesthetics. Hope you enjoy them. Get back to me if you would like to discuss.

Rainbows for the Fallen World
Germinal essays showing how imaginativity can invigorate daily life, including schooling, and why "allusivity" is key to artistry. The biblical charter for Christians making art is spelled out, and suggestions are given for working communally at a redemptive culture amid our brilliant, needy artworld.
