Unfortunately it’s abandonware now. It was called Showhopping and it would use the Scrobbler API and a list of your favorite bands and find out if any bands you might like (including the ones you listed) were playing in a given area any time soon. You could give it a location and a time range and it would give a list of shows playing on a map with a percentage back based on the likelihood that you’d enjoy the show. It was very lightweight with no sign up and I had it in mind people could use it like Yelp essentially, just ad-hoc.
