The Musicscene in Iran is very interesting.
There was a longer report about it in German ROCK HARD MAGAZINE a year ago.
Internet plays a really big role in bringing the music to the fans there and it is often the only way to make concerts.
Amazing is that the Iranian government years ago when the internet became technology... came up, was one of the leading nations in making it available to the public, they really supported it in the whole country, so that now Iran has a really good internet availability better maybe than some of the European countries.
It was already to late when they realized that they can not control it anymore, which now means that Iran has on of the best internet music scenes in the world.
