Step-by-step explanation:
Kazimir Malevich designed the costumes and set designs for the cubo-futurist opera Victory Over the Sun. This avant-garde opera is a notable part of the Russian avant-garde and constructivism movement, which generally involved itself with public art initiatives and often intersected with public life during the Civil War. Malevich's work, alongside others like Vladimir Tatlin, played a key role in public festivals and street designs, contributing to the ethos that art should engage directly in public life and have a social impact.
