This is really cool! If it gains traction it'd be neat to be able to see photos from events you've attended uploaded by other users as well.
Great idea. I've always been looking for a place to dump concert pictures so that everyone can enjoy them. Website looks really clean, kudos!
Neat idea. Can you plug this into setlist.fm, last.fm, and maybe SongKick to get some more data on each show?

Neat. Which framework are you using?
My story is similar to yours; googling to find the dates of concerts. Have you tried solving that part of the problem for your users? People remember a lot of details about the shows they see, but rarely do they remember the date.
Even if you manually created your own database for the dates, that would be a great start. It would be nice to select a band, then a location and be presented with a list of dates and venues they have performed at.
Also, there's a lot of bands missing from the auto-fill. Does that update as people continue to add more bands?
This is a great start.
