After the group ended its activity, Nemeček shortly played with one of the last lineups of Džentlmeni, before forming the progressive rock band Pop Mašina in 1972.

His musical heritage began with his great-grandfather, a gifted violinist who traveled from the Czech Republic at the end of the 19th century to join the royal orchestra in the Kingdom of Serbia.

[2] This tradition related to music continued through the following generations, with his grandfather Josip Nemeček, who played a key role in founding the Belgrade Philharmonic and worked as a lecturer and a performer at the Belgrade Opera, and father Jan.[2] The family's musical influence extended to Ludwig, Nemeček's uncle, who played jazz trumpet,[2] and Ludmila, his aunt, a dedicated member of the Belgrade Madrigalists.

[5] With Pop Mašina Nemeček recorded two studio albums and a live album—the band's debut debut Kiselina (Acid) today considered one of the most notable records in the history of Yugoslav rock music—before leaving the band in 1976 to serve his mandatory stint in the Yugoslav army, Pop Mašina continuing without him and eventually disbanding in 1978.

[6] He moved to London again from 1983 to 1988, where, among other things, he was a correspondent for various papers under the umbrella of Politika a.d., like RTV revija (Radio and Television Revue) and YU video.

[1][2] Nemeček started his career in television as becoming the film program editor at RTV Politika.

[6] In the 1990s he became the editor of film program on Television Pink,[6] introducing the Serbian public to The Simpsons, The X-Files, Friends, La Femme Nikita, The Sopranos and other series.
