Changes

In art school, Mills began creating artwork inspired by lyrics from Brian Eno songs, which were later used in the book ''More Dark Than Shark''. Starting in the 1980s, he was receiving commissions to create artwork for album covers. His style began to evolve from traditional drawing and painting into a more abstract collage-oriented style, with many organic elements and items from nature being used as materials. His paintings are sometimes seen as visually mirroring the ambient sounds of many of the albums he designs covers for. He has also made two albums of semi-ambient music under the name Undark, by creating sonic collages from unused sounds given to him by musicians he has connections with.
