I'd have to look to get the exact start date on this image. I know its been around 3 years now. Here's another very small area of the full size image which is around 20 ft. wide. I doubt anyone is bothering to make digital art this big. Most computers will crash if you try to edit an image this big. Even with a powerful workstation, i am having a serious amount of lag. What i did was isolate around 40 different sections that will be utilized as album covers to represents different aspects of the project. Once i get done with those i'll tie them back into the main image and then shore up any areas that don't mesh well. I even thought to isolate larger chunks once these smaller chunks are done, then mesh them back in. All to avoid lag so i can work efficiently. We will see how it turns out.
Here's a link to the bandwhore website so you can get an idea of what is going on and how many people are participating. There may be more people added. I'm not sure.
This project was never intended to be pretentious. Jim Ross simply wants to jam with his favorite musicians and organize it all into one organized thing. And the art is intended to be massive like the project. That is all. Make of it what you will.
