Add a link next to [no label], on release pages, that takes you to a search result page that searches for that 'album artist' + '[no label]'.

Example search result (Lana Del Ray)

Key points from @reosarevok:

"[no label] is meant to be effectively the same as “self released”"
"if a release is “official, [no label]” there’s very little else it could be but a self-released release"

This would be a way of browsing an artists self-releases, without resorting to Discogs "mess" of making a bogus label for each one.

With multiple album artists I imagine each would be added to the search string.
