As a young activist, Shahin's lyrics often conveyed strong and controversial messages about Iranian society. This attracted the disapproval of Iranian authorities and in 2004, the threat of persecution forced him to leave Iran.In 2005, Shahin moved to Germany. Dubbed the "angry bard", he continued to write and perform music that was critical of conditions in Iran: poverty, oppression of women, homophobia, censorship, ideological dogmas, violence and cultural taboos. For a time, his career veered into rap and hip hop, bringing him fame among young fans back in Iran. These days, Shahin's music fuses rock, jazz, and blues with lyrics that demand change.
