This may be related to Bug 1704. Will investigate.

Actually this looks more like Bug 4361. Jens, it appears that the files in question have disc number tags. Would you try removing the disc and discc tags temporarily from the files in question and see if you get the same behavior?

Yes, all files have disc and discc tags (ALL files on my disc have the count 1 in disc and discc).
I will try to remove it this eventing and report the result.

After removing DISC and DISCC, one Artist is fine (Suzi Quatro in this case), but the next artist will have the same problem (see below).
I don't want to remove all DISC and DISCC tags from my flac files. I cannot see why DISC and DISCC should have an impact on the database entry for ARTIST - ALBUM

Steven, would it be appropriate to dupe this with bug 4361?

Ping Steven :)

ping, steven

I'm thinking that this is the same as bug 4361.  However I noted in that bug that just having a DISC tag present will change the behavior.  Perhaps the description should be changed.  Please reopen if this behavior persists after bug 4361 is fixed.
