Who was Delkash the musical genius

At the time of Dallish’s activity, there was no composer to cooperate with him, so he could not sing ballads, but after singing every song on the radio, local songs such as “Robabejan,” “Maryamjan,” “Zahrajan,” “Amiri,” “Ranajan,” and… were greatly received by the audience, so that every Sunday when he performed on the radio, many people gathered in front of the radio building to see her. Ruhollah Khaleghi chose the stage name “Delkash” for Esmat Bagharpour when she started her serious artistic career. Delkash is the name of a corner of the satellite device.
