Iraj (Hossein Khajeh-Amiri), born on January 1, 1933, in Natanz, and one of the most renowned figures in Iranian vocal music, passed away at the age of 94 after several months of illness. He was born into an artistic and cultivated family; his ancestor was a celebrated singer during the era of Nasser al-Din Shah Qajar, and his father, who himself possessed a fine voice and was well-versed in the radifs (modal systems) of Persian music, devoted years to training his son’s voice.
