Iranian hip hop originates from Tehran, the country's capital city, although a number of experimental works were recorded earlier by diasporan Iranian musicians, particularly in Los Angeles. Iranian rappers started out by recording mixtapes. Some combined hip hop with Iranian elements, such as Iran's classical music. Hip hop music in Iran has often been an underground movement. On several occasions, recording studios have been shut down, websites have been blocked, and artists have been arrested. Only a few works have been officially approved by the Ministry of Culture and Islamic Guidance. Hip hop dance is also present in underground movements, with few performances having received limited permission. Iran's premier rap group, 021, named after the telephone area code of Tehran, was founded during the 1990s. Hichkas, the lead figure of this group, came to be one of Iran's earliest renowned rappers, and therefore nicknamed the Father of Persian Rap. His well-received album Jangale Asfalt, produced by Mahdyar Aghajani, was the first Iranian hip hop album. It incorporated a fusion with traditional Persian harmonies and contributed remarkably to the evolution of hip hop in Iran. The 021 music group was co-founded by the Yashar and Shayan duo, later renamed Vaajkhonyaa. Zedbazi, founded in April 2002, is regarded as the pioneer of gangsta rap in Iran. The band quickly gained a huge popularity among the youth, due mainly to their use of explicit lyrics, littered with profanity and depictions of sex and drug use. They are credited with starting a new movement in Iranian music. Bahram Nouraei, who was once arrested, was listed as one of the "50 People Shaping The Culture Of The Middle East" by HuffPost in August 2012. His most popular work, Inja Irane, was described as a "poignant critique of the country" by Rolling Stone. Yas was the first Iranian rapper to be authorized to perform in Iran. He reached national fame through his song CD ro Beshkan, which was written about an Iranian actress who was subjected to a sex tape scandal. On 21 December 2011, he was chosen by voters as the "Artist of the Week" on MTV, entitled "Tehran's Hard-Hitting MC". The restrictions have been more stringent on women. Salome MC, who started her career collaborating with Hichkas, was one of the first women to contribute to Iranian hip hop. She was named as an influential and "revolutionizing" artist by MTV and Time.
