It could do with providing some useful information when no results are found, and why it might not have returned any results (available regions, what is a "band", what is a "venue"). At the moment, when there are no results, the first thing you see is "How it works". This immediately prompts the thought "It doesn't".

I entered a date range of 1st August to 30th November. In the town, there was a major music festival at the end of August, and a currently popular band will be playing in the town's biggest theatre at the end of November.

I then tried London. apparently, for those four months, there are no bands playing in any venue in London, I even tried Wembley Arena.

The city box autocompleted both of my attempts, which led me to assume that they were valid places in your database. You might consider restricting that autocomplete to only allow places that have events you know about.

To start with, I can't get it do anything. I enter my city and dates, click "show me concerts" and then nothing. Maybe you're not handling zero results properly or something?

Cool idea.

EDIT: Remove comment on quotes, got confused and thought it was you guys down there, since they look so alike.

So sorry everyone. I just posted this and fell asleep immediately. It was on a $5 DO server. Scaling up now...

Failed to load resource: the server responded with a status of 500 (Server Error)

:(

Not working for me either, on chrome/mac.

Where are you getting the data from?
