Mira wrote and performed in the multimedia installation Up in the Attic by Mikołaj Sobczak. The song, written in collaboration with Andrzej Izdebski, is a modern requiem about the 16th century German theologian, reformer, printer and revolutionary Thomas Müntzer. The work was presented for the first time in Sobczak’s solo exhibition Leibeigene (2022) at Kunsthalle Münster and continues to be shown at different locations.
