Displaying Albums where Artist is AlbumArtist and also Trackartist

[stefano_mbp]

This is because when you retrieve John Coltrane (for example) as Artist (album artist) you’re filtering all albums where John Coltrane is Artist, then albums where Coltrane is only a track artist (and not the album artist) will be excluded.
Then this should work: Artist.merge={All Artists}
Of course this is a compromise as you’ll find under Artist (album artists) all track artists too.
Using your first post example you’ll be able to browse to Miles Davies as Artist (album artist) and you’ll be able to find under Artist all albums where Coltrane is album artist and track artist too (Miles Davies/John Coltrane albums included)
