I don't like Turkish music, or do I?

It’s quite possible you know all this already, however, on the outside chance that you don’t:

Going by Discogs, it looks like the Istanbul-based Kalan Müzik label obtained a license to release this album in Turkey the next year (1995).

Over the past 25+ years, this label has acquired quite a reputation for curating and releasing all kinds of early and mid-20th century music from Turkey. The cd’s of theirs that I have (late 90s/early 00s releases) all came with quite lavish hardcover booklets, although unfortunately the information provided on recording and release dates is scattershot at best.

Still, I’d say it’s definitely worth a shot getting in touch with them. As it says on their website:
“Kalan Music has, with the assistance of expert musicologists, compiled and issued albums of unusual and ethnically varied works that are considered important to Turkish music history. As well as being appreciated by classical Turkish music lovers, academics have found these records invaluable for use as sources in international studies of ethnomusicology.”

Furthermore, many of the tracks on that Istanbul 1925 album can also be found on other compilations (in some cases with slightly differing spellings/transliterations for artist names and/or song titles), giving you perhaps another inroad.

These two for example are both on FM Records, a Greek label:

Thanks breastcrawl, sorry I missed your reply earlier - that's really helpful.
