OP here: Hi there! I have built an interactive web app where you can choose any artist that you love and quickly find out who's in that band (if you choose a band) or what bands are related to an artist (if you choose a person)
You can also spawn the artist's related artists from Spotify and build a really big web of relationships and find, for instance, bands that are in the intersection between other bands.
Let me know what you think of it!
