"It’s like collaboration between the state and those thugs - the authorities wouldn’t tolerate forms of art that fail to support the official state line and these thugs will do the dirty work, threatening and beating up artists, who have alternative views. The state is interested in the existence of these attackers who will only find more encouragement. No one, apart from the victims, is interested in the investigation."
Kremnev says that the Russian state censure on art has become gradually stricter since 2011, but got really intensive since the start of the Ukraine crisis.
"A popular Russian singer Diana Arbenina sang in Kiev recently and she was banned performing in Russia afterwards. This is just an example – the cultural ideology has become entirely anti-Western in Russia," he complains.
"The artists who are trying to do something that is not approved by the authorities, are vulnerable to physical and other attacks. The situation has become especially unbearable in St. Petersburg. If traditionally the city was considered to be the cultural capital of Russia, then lately it has become to be known as the capital of suffering."
"St. Petersburg is full of extreme nationalist groups that are neo-Nazi in nature. They are not following Hitler’s Nazism, but their ideology does not differ much from fascism. Many members of those militant groups have gone to fight with pro-Russian rebels in east Ukraine. They were already dangerous before, but what will happen upon their return?" Kremnev asks rhetorically.
Kremnev reckons that his attackers stemmed also from one of the neo-Nazi groups in St. Petersburg.
In the meantime, he is planning to stay in the Estonian capital, at least until Russia returns to normality.
"My grandparents used to live in Tallinn and it was easy and convenient to come here. I’m afraid to return to Russia," he says.
