I thought that something a little less focused on the actual furnaces could be a fresh take - this concept is inspired by this old steam engine thats laid up by the furnaces. The lineup would go along the bottom in perspective where the tracks would be. The engine is flanked by colorful plants and flowers, with a burst of bright swirling steam coming from the top. I think this direction could be really awesome done in a bold, bright, colorful style similar to this poster we did last year.
I've been developing this new collage style that I think could be really great for this poster. This would be a semi-abstracted collage illustration of the furnaces and water tower - each collaged piece could have a different photograph, pattern, texture, illustration etc that relates to the vibe of the event. The lineup could go on the large piece at the bottom. Here are a few examples of other thingswe've donein this style.
This was a sketch I did for the poster last year but I still really like it! Pretty straightforward - lineup at the bottom, simple illustrated furnaces above with a large psychedelic steam cloud rising from it. The majority of the composition is taken up by a bold type treatment interlocking with the colorful steam rising from the furnaces.
