Before creating a new “CSG side-effect? release (group)s don’t appear in artist pages” topic I searched for existing topics and found this one. 
So I have this 100 track compilation that includes track 4.13: Cavatina by Barrios, played by Manuel Barrueco and Steve Morse.
So Manuel Barrueco is indeed marked as part of my collection.
But I had difficulty to find what CD this artist was on, even if the guitarist is a recording artist (not only a relationship):
- The full list of release groups didn’t show me
- The full list of releases (more pages) didn’t show me either
- I had to search the list of recordings (that can be a very very long list for some artists) to eventually find a marked recording and find my release
It’s not a big hinder for me, as I have very few CSG CD.
But just sharing my experience.
