Laboratorija Zvuka were a prominent act of the Yugoslav rock scene, noted for their eccentric style, erotic lyrics, unusual line ups and bizarre circus-inspired stage performances.

In the late 1980s, the band, although never officially disbanding, retired from scene, as Vranešević brothers dedicated themselves to music for film, theatre and radio and TV shows.

[1] Their songs had unusual titles—for instance, "Intelektualno sakupljanje jabuka u dolini senki" ("Intelectual Apple Gathering in the Valley of Shadows")—and were influenced by mysticism.

[1] They debuted with music for Karpo Godina's 1971 short film Zdravi ljudi za razonodu (Healthy People for Recreation), composed on the lyrics of poet and musician Branko Andrić.

[1] During the years, they wrote music for over 150 films, most prominently for Karpo Godina's The Medusa Raft and Artificial Paradise, Dragan Kresoja's One Last Time, The End of the War, Oktoberfest, The Original of the Forgery, Full Moon Over Belgrade, and numerous TV shows, including popular children's shows Poletarac (Nestling), Priče iz Nepričave (Stories from Nepričava), Fore i fazoni (Jokes and Gags) and Čik pogodi ko sam (Guess Who I Am).

[1] Five years earlier, the brothers and Žilnik tried to produce their rock opera Fabrike radnicima (Factories to the Workers) in Atelje 212 theatre, but were—despite positive reactions by prominent figures involved in the theatre's work, like writers Jovan Ćirilov and Borislav Mihajlović Mihiz, director Borka Pavićević and actor Zoran Radmilović—refused by managing director Mira Trailović due to the play being overly politically provocative.

[1] Later during the year, the band released a 7-inch single which brought their biggest hit, the ska song "Ska-kavac joj zaš'o u rukavac" ("Grasshopper Got in Her Sleeve"), which featured quotes from Crven ban, a collection of erotic folk poetry compiled by Vuk Stefanović Karadžić.

[1] The band's following album, Duboko u tebi (Deep inside You), was released through Jugoton in 1982 and featured the cover designed by renowned comic book artist Igor Kordej.

[1] The album also featured a cover of Larry Williams' "Bony Moronie", and "Odlazim dolazim" ("I'm Leaving I'm Coming"), the latter recorded live in 1978 on the band's performance at the Subotica Youth Festival.

[1] In 1982, the band performed in West Germany, on the concerts organized by Cultural and Educational Trust of Vojvodina for the children of Yugoslav guest workers.

[1] Some citizens of Novo Mesto saw a poster announcing Laboratorija Zvuka concert in the city, depicting naked Vilmoš Kauboj with a hat similar to the ones often worn by late President of Yugoslavia Josip Broz Tito.

[1] The consequent trial resulted in Predrag Vranešević initially being sentenced to 40 days in prison, but the whole case was soon hushed up as absurd and the charges were dropped.

[1] The happening, entitled Jašući konje Svetog Marka (Riding the Horses of Saint Mark), featured an art exhibition and a theatre play about a hero named PVC, "the illegitimate son of Sergei Yesenin and Isadora Duncan".

[1] During their staying in London, the band recorded a short documentary, entitled Kuda ide naše malo društvo (Where Is Our Small Society Heading To), with the screenplay written by Predrag, and directed by Mladen Vranešević.

[10] Beside new material, the album featured new versions of songs "Ska-kavac joj zašo u rukavac", "Devica" and "Šetnja", originally released on the band's 7-inch singles.

[9] After the album release, Vranešević brothers dedicated themselves to composing for film, theatre and television, and the band, although officially still active, appeared in media sporadically only.

[11] After a longer break in their work, the band, in 1996, released the album entitled in Serbian ijekavian, Nema niđe te ljepote (There's No Such a Beauty), through Komuna.

[9] The album featured the song "Čudnan susret u tmurno popodne" ("A Strange Encounter during the Gloomy Afternoon"), originally performed by Vranešević brother's old band Med.

[9] In 2014, Ira Prodanov Krajišnik and Živko Popović published the monograph Ulaz slobodan (Free Entrance) about Predrag Vranešević's work on theatre music.

[13] Deže Molnar, after Laboratorija Zvuka ended its activity, performed with numerous artists, including Tony Scott, Milan Mladenović, Mitar Subotić, Aleksandar Dujin, and others.

[9] Serbian pub rock band Optimal Problem recorded a cover of the theme song for the TV show Poletarac for their 2017 album Ispred svih (Better than All).
