This past weekend at Higher Ground Music Festival we hung out a bit with a friend of ours named Eric Samuel Timm of NOU (No One Underground).  He is a brilliant communicator, creatively combining speaking with painting and music.  He speaks at some of the biggest youth events in the nation, and is one of the best speakers I've ever heard.  Love his videos on YouTube too, like this one below.  More info or to purchase his paintings, go to NoOneUnderground.com.
