No one knows about Persian Cats (2009), director Bahman Ghobadi

The film portrays a surprisingly vibrant youth culture in Tehran. It is
filmed in documentary style, without government permission and hand-held
cameras. The storyline is very simple: With the help of their manager
Nadar, two young indie rockers Negar and Ashkan look for passports,
visas and band members to play at a London concert. As part of their
quest, we are shown the full breadth of the music scene in Teheran, from
rap to indie rock. The bands portrayed, who all play themselves, produce
an excellent soundtrack. Although police oppression and poverty lurk in
the background, this is basically a very optimistic film, carried by the
courage, energy, creative power and liberal attitudes of the
protagonists.
