How can songs reflect political events? How does a song become a political song? The artist Olaf Nicolai invited eleven international composers to write songs that reference political events which were of current relevance to them. Without prior announcement, a total of 58 songs were performed as a-cappella pieces on twelve Sundays in 2011 on the central staircase of the Pinakothek der Moderne in Munich. Visitors to the museum found themselves as actors in a staged performance for brief instances of time. The publication Escalier du Chant presents excerpts from the songs and commentaries by the composers in the form of 58 music sheets; the accompanying booklet contains various photographs of the performances. Includes songs by Tony Conrad, Georg Friedrich Haas, Georg Katzer, Liza Lim, Samir Odeh-Tamimi, Enno Poppe with Marcel Beyer, Rolf Riehm, James Saunders, Elliott Sharp, Mika Vainio, Jennifer Walshe.
