Songkick API

From their site: At Songkick we've spent a lot of time collecting data about live music, and now we want to see what you can do with it. We're currently putting together an API to allow access to much of the data available on the website. This is very much a work in progress, but we're making what we have available as a preview to participants in the Music Hack Day taking place over the weekend of July 11th and 12th 2009.
