The Plastic People of the Universe is a rock band from Prague, Czech Republic. It was the foremost representative of Prague's underground culture (1968-1989). This avant-garde group went against the grain of the Communist regime and due to its non-conformism often suffered serious problems such as arrests. The group continues to perform even after the death of the founder, main composer and bass player, Milan Hlavsa. Going on before them will be the cult Croatian avant-garde band, Tigrova Mast, reunited and crazier than ever.
