Nazeri began studying radif, the classical Persian repertoire, and worked with some of the masters of modern Persian music, including Abdollah Davami, Nourali Borouman, and Mahmoud Karimi. He also studied to play the tar (a stringed instrument) with Habibollah Salehi. In 1969 he issued his first recording.
In the early twenty-first century he specializes in singing the words of such Sufi writers as Jalal al-Din al-Rumi, Shaykh Attar, and Hafiz of Shiraz. Called the Persian Nightingale and the Pavarotti of Iran, Nazeri sings in both Persian and Kurdish, and has worked with Aref and Sheyda, the leading ensembles in Iran.
