Amir Mansours opinion
about this recording:
 

Dear Pooyan,

All of Sheikh Karnas recordings were recorded in 1928. This track is the re-performance of a recording by Sheikh Sheipour for Gramophone company in 1906.
"Salehi" is Tar player in this record.
For photos of Sheikh Karna & Sheikh Sheipour look at Iranian rare photos akshaye_ghadimiby Ghassem Saufi (Tehran University publication) & "Rejal-e Iran" by "Mahmoud Mahmoud" (Zawwar publication).
