Univ.-Prof. Dr. F. M. von Hornbostel recorded all the tracks in field researches.
This is the seventh map from the whole Hornbostel repertoire and part of the 12-disc collection "Musik des Orients".
MrShellac comments: I own two full Maps of all records from that series (everything in A+ condtion), one signed by himself and the handwriting on the Label is his.
