Add "Store Norske Leksikon" to "other databases" (or other more appropriate linktype)
Large Norwegian Lexicon, is a online encyclopedia in Norwegian.

example: https://snl.no/Ruth_Bakke

This would be for ostensibly Composers and artists/groups, however as a leksikon (encyclopedia basically) it'd have pages on anything, including instruments and places, maybe even some select works.
it would perhaps be useful for exclusively Norwegian such.
