This handy website takes your publicly available listening data from last.fm and shows where the artists you listen to are located in the world. It's a great opportunity to find artists in specific cities and reach out to ask for support - or even arrange a collaboration while you're in their city.
Of course, if you haven't used last.fm this won't really benefit you at this time. However, if you know someone with a similar listening history, you can still enter their username and discover some cool bands through the app. Neat trick, huh?
