released in 2000. Although the PPU were not associated with politics, the Communist regime's accusations against them led to various protests. It was partly in response to the arrests and prosecutions that playwright Václav Havel and others wrote Charter 77. The trial of the Plastics became a milestone for opposition against the Communist regime in Czechoslovakia. In 1978, PPU recorded the Easter-themed album Pašijové hry velikonoční (released in Canada as The Passion Play by Paul Wilson's imprint, Boží Mlýn Productions). Jak bude po smrti, which set the poetry of Ladislav Klíma to music, followed in 1979, and Co znamená vésti koně in 1980. In 1982, Brabenec was forced by the secret police to leave the country as part of Akce Asanace ("sanitation act"), and emigrated to Canada. After his departure, the band released the albums Hovězí porážka in 1983 and Půlnoční myš in 1986. At the time, PPU included clarinetist Petr Placák, cellist Tomáš Schilla, guitarist Milan Schelinger (brother of Jiří Schelinger), and vocalist Michaela Pohanková. Despite their clashes with the government, the musicians never considered themselves activists and always claimed that they wanted only to play their music.

This led to disputes between the band members and eventually, the group broke up. Hlavsa, Janíček, and Kabeš formed the group Půlnoc, which played publicly from 1988 and was even allowed to tour the United States a year later. Půlnoc recorded two albums in the early 1990s. Reunion, Hlavsa's death, and continuation: 1997–2014 After the Velvet Revolution, in 1989, the only concert PPU held was in 1992, with the old lineup of Hlavsa, Janíček, Števich, Jernek, and Zeman. This was recorded, and released as Bez ohňů je underground in 1993. In 1997, Hlavsa, in collaboration with Jan Vozáry (Oceán), released the live album Magické noci 1997, which included older Plastic People songs in a modern electronic arrangement. The album wasn't released until 2021. Also in 1997, upon President Havel's suggestion, PPU reunited in honor of the twentieth anniversary of Charter 77. Their lineup consisted of Hlavsa, Brabenec, Janíček, Kabeš, Brabec, as well as Joe Karafiát. They released the live album The Plastic People of the Universe the same year and continued to tour. In 1999, along with Lou Reed, PPU performed at the White House during Václav Havel's state
