The show I was going to reccomend was Pat McCurdy, <a href="http://patmccurdy.com">
Website </a> but unfortunately he is playing a private party the night of the fourth. FYI he's a one man show, just him and a guitar, very difficult to describe. Lots of goofy funny (sometimes interactive)songs about love, sex, relationships,(both good and bad ones) drinking, religion, politics and everything else under the sun.
It's a shame you won't get to experience the controlled insanity that we in Milwaukee know simply as a "Pat Show."

(Hopefully it will work, if not I can email it to you if you like)
