Have you considered linking the concert as “extra” to your regular music library?
If you store the videos in a dedicated clips section or alongside your music library, the music videos will show on the artist page and music videos will be linked to matching tracks of that artist.
Using this mechanism, Plex will distinguish regular music clips, concerts, live music videos, lyrics music videos but also interviews or behind-the-scenes videos.
