The legendary Russian rock band Aquarium gave an unexpected gig in an underground passage in Omsk on February 23.

      

      The day before, on February 22, the musicians appeared on the stage of the Omsk Concert Hall. During the concert the band's frontman Boris Grebenshchikov promised the audience to perform in one of the underground walkways of Omsk on February 23. He did not exposit the exact place of the surprise gig, however.

      

      The fans occupied all underground walkways in the downtown from early morning. The majority of people flocked in the most capacious pedestrian subway in Omsk, by the Pushkin Library.

      

      But the musicians arrived at the pedway near the Shopping Mall at about noon.

      According to lucky eyewitnesses, The Aquarium played their hits for about half an hour and raised nearly 10 thousand rubles.

      

      Right after the performance the band headed to the train station: the tour will go on in Novosibirsk.
