I have not been able to find anything about this Turkish 78 except for the name? of the performers? which is written in English on the label. An intense piece of music which a scratchy recording only serves to make even scarier, it has voices, an insistent hand drum and the horn/flute instrument sounds like an ancient mey. A captivating, maybe uneasy listen (war song?heroic allegory?),this appears to be from the late 1910s, on Victor’s “bat wing” label.

I think you couldn’t find the names of the performers, either. The title is written in English “seni gördükçe titriyor yüreğim”, and it is a love song.
The song is a “kanto”, which was a kind of popular music of Istanbul. And the instrument is “zurna”, played by famous Arap Mehmet. One of the singers is Gülistan Hanım, a famous kanto singer of her time. Other singer’s name is not written. Maybe a better photo may provide more information, since the small Arabic letters are unreadable.
