Warren started this jam over twenty years ago to benefit Habitat for Humanity. Each year it attracts awesome national musicians and people who come back year after year to just experience a great event in a very cool city, all for a great cause. I think each year is very different but I can say every year is fabulous fun! It is hard to describe in print! I will say go out and look on etree for the audio. There are many people always recording these great shows. http://www.etree.org/
