After their fame, garnered from appearances on the radio show "Pokaži kaj znaš" (Show what you know), appearances at various locations in the Dolenska region, and their first few recordings on radio, the Lojze Slak Trio, consisting of Lojze Slak on the button box, Niko Zlobko on guitar, and Ciril Babnik on double bass, released their first record from the RTB recording studio in Belgrade, and christened it with the waltz Domaci Vasici. It was at this time that they met up with the singing quintet, Fantje s Praprotna (Boys from Praprotna), with whom they were soon rehearsing together. The legend of the Lojze Slak Ensemble, which would soon be known and recognized worldwide, had come to life.
The new Lojze Slak Ensemble made their first public appearance at a January truck drivers convention, held in a theatre near Slog. In their new form, the ensemble began recording new material, and very soon dominated the radio waves with their beloved music. They recorded and released their first LP record at the recording studio Jugoton, the most prominent recording studio in the country at the time, featuring all original music written by Lojze Slak. The album featured the hit title track "Kadar pa mim' hišce grem" (When I pass by the house).
The formal recognition for the ensemble was starting. Their first award was a silver record, for sales of 50,000 copies of their Domaci Vasici record, received by Lojze and his ensemble from the recording studio RTB. At the end of the year, they received another Silver Record award, this time from the Jugoton recording studios, for exceeding 50,000 sales of their LP "Kadar pa mim' hišce grem" (When I pass by the house).
The Slak musicians cooperated with the film producer/director France Kosmac in the creation of the full length film "Lucija". They also went on tour, crisscrossing all of Slovenia. With assistance from the government organization Slovenska Izseljenska Matica, they also went on tour to neighboring countries in Europe, playing their beloved tunes to Slovenian expatriates on their first concert appearances abroad.
The Slak ensemble filmed their first television special on Trška Gora and surrounding areas in the Dolenska region. They also appeared and recorded for radio broadcasts, and by the summer, had accumulated enough new material to release two more albums, entitled "Na Ohceti" (At the wedding), and "Deželica Sonca in Grozdja" (Land of sunshine and grapes). In the fall, they released their third album of the year, entitled "Sinko, ne sprašuj" (Son, don't ask).
The ensemble performed at concerts, banquets, and various shows, all of which were sold out to the end of the year. They also released two more albums: "Pod to goro zeleno" (Under this green mountain), and "Po Dekle" (For the girl). At the 25th anniversary of Avnoj in Jajc, Lojze Slak and his ensemble performed for president Tito and his guests, after which he was also invited to perform and record all over the country of Jugoslavia.
The record "Kadar pa mim' hišce grem" (When I pass by the house) had by this time exceeded 100,000 in sales, and for this, the ensemble was presented with a Golden record award.
More awards - the Slak ensemble had sold over a million records, and for this they were presented with the Zlata Čaplja (Golden Heron) award from the Zagreb recording studio Jugoton. They also won the Golden Swallow award on the program Antena, for best folk group.
They also released another album, this time entitled "Triglav", and were featured on the Tivoli television broadcast of "Polke in Valčki" (Polkas and Waltzes).
This year, the ensemble began recording in the Helidon studios, releasing their first album under the new label, entitled "Titanik" (Titanic), followed soon by another album, entitled "Visoko nad oblaki" (High above the clouds). With these two albums, they embarked on their first North American tour, playing for their Slovenian fans in the USA and Canada. They were so well received in North America that the tours had to be repeated every five years from then on.
The Slak influence put Slovenians in the world spotlight. At the music festival in Ptuj, the button box surpassed the piano accordion in popularity, while in North America, Slak's tour caused a small instrumental revolution. Button box bands started to sprout like mushrooms in the rain. Even some orchestras started adopting the button box as a regular instrument. Button boxes were desired for souvenirs, as well as their unique sound.
In a contest in the magazines Stop and 3x3 Naj, the Lojze Slak ensemble was selected as the best and most beloved musical band for folk music, while the Fantje s Praprotna were selected as the best vocal group.
With their new album "Pod gorjanci je otoček" (There's an island below the mountans), the Slak ensemble embarked on a two month tour amongst their many fans in Australia. In November of that same year, they toured the countries of western Europe, playing for fans in France, Belgium, The Netherlands, West Germany, and Switzerland.
For their incredible sales success, the Slak ensemble was once again awarded a Golden Record from the Jugoton label. At the same time, they had released a new record under the Helidon label, entitled "Glas Harmonike" (Sound of the Accordion), while a new record label released a double cassette tape of many of their hits, and entitled it "Iz Slakove Skrinje" (From the Slak Cupboards).
Because of all the success with their record sales, the Slak ensemble was once again one of the most beloved and influential exporters of Slovenian music.
