Russian political activist rockstar Yuri Shevchuk plays in UK
In the 1980s Russian rock musician Yuri Shevchuk was persecuted by the Soviet authorities and his music was driven underground.
In the 1990s he became one of the country's biggest music stars.
Now he is often described as "the conscience and the voice of the nation", and his active involvement in political opposition lead many to believe that he could challenge Vladimir Putin in last month's presidential election.
Shevchuk and his band DDT recently brought their ambitious new show to a packed HMV Apollo in London.
