I'm building Concert Map [1], an interactive map of live music events all over the world.

I was frustrated with how difficult it was to find concerts and festivals when travel plans are flexible. Questions like:

- Is there any show I could catch on my next cross country road trip?

- I want an excuse to visit Seattle this summer, is there a good weekend I could pick where I could see live music there or along the way?

- I like to travel for one big music festival per year, is there a good match for me anywhere in the country, or abroad?

The idea behind concert map is to show all events on a map, and highlight the "most relevant" events for any area, so you can skim through the map and find events that are worth the travel. The "relevant" events depend on the view context. If you import your top artists, then the most relevant events are ones with artists that you listen to most. Otherwise, it's based on global artist popularity.

I'm currently working on integrating with more event providers, and working on loading performance. I've been using leaflet.js [2] which has worked great, but I'm experimenting with switching to supercluster [3].
