The festival organizers have reported about it on the official site of the project. It is underlined that it will be the only performance of the popular band in Russia. By the way, System of a Down came to perform in Russia only once before.

System of a Down won popularity around the world, however, despite success, in 2006 the band members announced a sabbatical leave and they did not perform together for nearly 5 years. This year the musicians plan to release their new album, which will be the first one in the last 8 years.
