Thousands of red chairs are standing empty along Sarajevo’s main avenue on Friday as Bosnia and Herzegovina commemorates the 20th anniversary since the start of the country’s war. A classical orchestra will play a concert for the 11,541 empty seats, one for each civilian killed during a near-four-year siege of the city by Bosnian Serb forces, which became a symbol of the 1992-1995 conflict.

It’s a piece called “Red Chair Blues” about anxiety regarding bleeding onto chairs during The Time.
