I think this is a good idea but I don't think it's going to work as well as intended and here is why. It offers all the information a listener, or fan might want to know about an artist although it doesn't allow artists to incorporate their identity into their page. The overall feeling of the design and interface looks like a directory where you'd look through multiple artists pages to find something out, rather than being taken to this page from say an artists Instagram or YouTube pages.
I feel as though there needs to be much more design options available to truly make these pages feel unique and allow for people to discover similar artists whilst browsing these pages to make the content feel more valuable to them. I think it's a good start but I'm not sure how and when I'd use this to stay up to date with artists.
Perhaps there needs to be feed integration with other platforms so it can be used as a one stop hub for fans? Otherwise I feel this information is easily seen on Apple Music, Spotify & YouTube Music pages anyway.
I do hope this was constructive and your launch goes well.
