On the topic of digital expressionistic painting, here's an essay I wrote for Art Papers twelve years ago that I hadn't looked at in a while.
Very little of the thinking (ranting) there would be revised after all this time. And the digi-paintings covered look much like the work being done now.
Was advocating a multi-platform approach, not in the context of branding but in wanting visual art to be more like drum and bass and hiphop: a sampling aesthetic but also eclecticism of means, where one software program interrogates another within the same work (e.g.. Illustrator quasi-vector rubbing up against Photoshop bitmaps, text smeared into visual content, etc.).
