Iranian conductor returns home

Last month the Tehran Symphony Orchestra gave its first concert since it was disbanded nearly three years ago. Although it was founded some eighty years ago and in that time, survived the coup of the 1950s, war with Iraq and even the Islamic Revolution, it finally closed under the last president Mahmoud Ahmadinejad, neglected and starved of cash. It's now been resurrected, under the leadership of the principal conductor, Alexander Rahbari . Why did he decide to return?
