In the minds of many foreigners, Slovenian folk music means a form of polka that is still popular today, especially among expatriates and their descendants.
In 1701, Johann Berthold von Höffer (1667–1718), a nobleman and amateur composer from Ljubljana, founded the Academia Philharmonicorum Labacensis based on Italian models.
The first major Slovenian opera was performed in 1732, Il Tamerlano by abbate Giuseppe Clemente de Bonomi, maestro di Capella, in the palace of the Carniolan vice-regent, the duke Francesco Antonio Sigifrid Della Torre e Valassina.
Composers of Slovenian Lieder and art songs include Emil Adamič (1877–1936), Fran Gerbič (1840–1917), Alojz Geržinič (1915–2008), Benjamin Ipavec (1829–1908), Davorin Jenko (1835–1914), Anton Lajovic (1878–1960), Kamilo Mašek (1831–1859), Josip Pavčič (1870–1949), Zorko Prelovec (1887–1939), and Lucijan Marija Škerjanc (1900–1973).
In the early 20th century, impressionism was spreading across Slovenia, which soon produced composers Marij Kogoj and Slavko Osterc.
Avant-garde classical music arose in Slovenia in the 1960s, largely due to the work of Uroš Krek, Dane Škerl, Primož Ramovš and Ivo Petrić, who also conducted the Slavko Osterc Ensemble.
Contemporary classic music composers include Uroš Rojko, Tomaž Svete, Brina Jež-Brezavšček and Aldo Kumar.
From 1952 on, the Slavko Avsenik's band began to appear in broadcasts, movies, and concerts all over the West Germany, inventing the original "Oberkrainer" sound that has become the primary vehicle of ethnic musical expression not only in Slovenia, but also in Germany, Austria, Switzerland, and in the Benelux, spawning hundreds of Alpine orchestras in the process.
Avsenik's most popular instrumental composition is the polka that is titled "Na Golici" (in Slovene), or "Trompetenecho" (in German), and "Trumpet Echoes" (in English).
Other popular bands, most largely unknown outside the country, include Tabu, ManuElla, Društvo Mrtvih Pesnikov (pop-rock), Siddharta, Rok 'n' Band, Pop Design, Fredi Miler, Terrafolk, Leaf Fat (screamo), Amaya, Šank Rock, Big Foot Mama, Yogurt, Dan D, Zablujena generacija, Katalena, Devil Doll (experimental rock), Negligence (band), Chateau, Čuki, Zaklonišče Prepeva, Psycho-Path, Dekadent (black metal), Buldožer (progressive rock) and Joker Out.
After 1990, Adi Smolar, Iztok Mlakar, Vita Mavrič, Vlado Kreslin, Zoran Predin, Peter Lovšin, and Magnifico have been popular in Slovenia, as well.
The most famous representatives of this genre were Pankrti, Niet, Lublanski Psi, Kuzle, Čao Pičke, Via Ofenziva, Tožibabe, and Otroci Socializma.
Other NSK member groups include IRWIN (visual art), Noordung (theater; originally named Scipion Nasice Sisters Theatre, also known as Red Pilot), New Collective Studio (graphics; also known as New Collectivism), Retrovision (film and video), and the Department of Pure and Applied Philosophy (theory).
The NSK were the subject of a 1996 documentary film written and directed by Michael Benson, entitled Prerokbe Ognja in Slovenian, or Predictions of Fire in English.
They issue passports,[19] have presented shows of their work in the guise of an embassy or even as a territory of their supposed state, and maintain consulates in several cities including Umag, Croatia.
Laibach's version of the NSK anthem includes a computer voice reciting an excerpt from Winston Churchill's famous "We shall fight them on the beaches/We shall never surrender" speech.
Laibach represents the music wing of the Neue Slowenische Kunst (NSK) art collective, of which it was a founding member in 1984.
