I have a couple of releases credited to Otto Winter
A disc look up takes me to releases credited to Miklós Spányi
I just entered this merge, which on the release group level only credits Bach, but the individual releases often have one or the other of his names on the cover. The only difference seems to be that Otto Winter is used on the English-language releases. Wouldn’t it just be an alias?
Update: I went ahead and entered a merge for the two.
