The group featured Jim Čert, a Czech accordion-playing folk singer and Jaroslav Erno Šedivý, a Czech drummer noted for his collaborative work with the Plastic People of the Universe, and four American musicians involved in the Bay Area rock scene.
Čert and Šedivý, active on the Czech music scene in the 1980s, were known for their dissent against the communist regime in that country.
Both were jailed several times for making music deemed "anti-social" by the government, who would not let musicians perform without state approval.
[citation needed] The band caught the attention of San Francisco musician and political activist Jello Biafra, former frontman of the hardcore punk band Dead Kennedys and head of the Alternative Tentacles record label.
The material on these two releases consisted of songs written by Čert, including "Marijuana", with lyrics by pro-marijuana activist David Peel.
