CatfishSmooth is a website that finds connections between music artists. For each artist, you will see the type of "similar artist" recommendations to which you are accustom. 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.
