Mohammad Reza Shajarian embodied the timeless beauty of Persian music

The singer, who has died aged 80, was silenced in his home nation for his outspoken criticism - but his artistry played on in the hearts of Iranians at home and abroad

I vividly remember the first time I met Mohammad Reza Shajarian on a summer afternoon in Berlin in 2011. He was touring Europe, along with his daughter Mojgan and an ensemble of young musicians. For Iranians, this was - along with North America - the only place they could experience their great idol on stage, given that the outspoken maestro of Persian classical music had been banned from performing inside Iran two years earlier.
