I like the inclusion of local (IP-based?) results -- you should make those more prominent IMHO. At first I mistook them for Adsense, but it really makes sense to automatically find tickets for the closest venues for upcoming events.
On the ticket searching page, I would expect it to be ajax goodness — yet it wants to keep reloading the full page for every option change. I don't like that.
The homepage — ticket buying visitors likely don't give a crap about anything but the search box and the "upcoming events" bit. Personally, I would treat the site as as just that — a site — rather than an app. Put some cool info and links to events on the homepage, to attract the people who are interested in what your service providers, but are not there exclusively for any tickets at that time; give them something to look at, and they will be more likely to return WHEN they need to buy tickets.
Maybe your being too much like Google, how many times does the average person search a day — compared to how many times they buy tickets? People always have something to search for, so Google quickly gets people coming back. You on the other hand, have to try harder to get people to remember you.
you need a major redesign for the main page. I know you are trying to go for the simplicity of Google, but flashy design seems pretty important for the space you are in.
Also your layout jumps to the left after you leave the homepage. So its kinda odd
