This site is all about connections between music artists. In a sense, it is a music artist recommendation system but more. For each artist, you will see the type of "similar artist" recommendations to which you are accustomed - we use last.fm and The Echo Nest to get these. But you will also see some other inter-artist connections catfish has discovered from the web of linked data. These include things like "artists that are also English Male Singers" or "artists that are also Converts To Islam" or "artists that are also People From St.Louis, Missouri". And, hopefully, you'll get some media for each artist so you can have a listen.
