"You are the voice of Iran - for the people of Iran!" The singer says, "I am an Iranian child... with one voice we sing, everyone with one voice: Iran! Iran! Iran!" The chorus is simply a mass of hundreds cheering "Iran! Iran! Iran!", the music video depicts Persians of all ages dancing and cheering. But the flags they are waving say "IRAN" across the white band in the middle, instead of the coat of arms of Iran, which spells the name of God with the sword of the revolution. The flag waved in the video also lacks the twenty-two iterations of "Allahu Akbar" (God is Great) along the border of the white part of the flag (see image)
Displaying the flag of Iran without the additions approved by the revolution is a common method of expatriates to show disapproval of the current Islamic regime.
So, curious, I searched for Arash in the archives of the Tehran Times. Nothing. I shouldn't be surprised. As an arm of Iranian government, Tehran Times probably can't discuss any hint of dissent.
It is a strange mix - patriotism and dissent. Or perhaps dissent is the most powerful form of patriotism.
On a side note, Washington Post hasn't heard of Arash, unlike their European counterparts.
