The Artist page wastes a lot of space because the photo is above the bio.
Can’t you have an alternate layout which is similar to the Album page, whereby the bio is to the right of the photo?
Give the user an option to choose which layout they want to use.
edit: Oh I see! Some Artists have a “wallpaper” (that takes up all the width of screen, looks good) and some only have a small “portrait”, didn’t realize. Guess it looks fine the way it is…
