Our interface went through many design iterations over the course of the term, and we feel it's improved significantly since its inception. We haven't found a good source of consolidated concert information with a good UI yet. Last.fm, Songkick,BandsInTown all have the same data, but they present the concerts as a list. The calendar interface with coloring by price and filtering by age is a simpler, more intuitive way of navigating concerts than a list or word cloud, and the artist similarity and friend visualization provide a more interesting view.
