Some of my favorite bands they often have there are three old guys playing some brass and maybe a banjo. These Old Guy Bands, as I call them, I really enjoy. The Dixieland tent at Jazzfest is my favorite as well. Here's a crappy iPhone pic of the signage outside if you're looking for it:
Saturday night they had Richard Scott and Friends playing, and I quite enjoyed the set. (If you go to Fritzel's site, as of this moment the music that plays is Richard Scott if you want to check it out.) Man I love this place.
