I've personally attempted to pitch people on seeing Jonathan Goldstein at Club Congress for a few months now, since the show was announced by Stateside Presents, and the general problem is explaining what it is he does exactly. He has a radio show in Canada (Wiretap) that you can hear in Arizona only on satellite radio or via podcast. He has a book out. He's been on This American Life quite a bit. He'll read some things, that will be funny, sometimes in a laugh out loud way, show a video featuring post-it notes, take some questions. It will be entertaining, if you enjoy smart people with dry senses of humor talking.
Summary: If David Sedaris was coming to a Tucson area nightclub, would you go? Then you should see Jonathan Goldstein. Not the same thing for sure, but close enough for your entertainment.
