Koncert mladosti (literally "Concert of Youth") was Czechoslovak music festival, only two editions of which were held in 1976 andà1977 at theàamphitheater in Pezinok, Slovakia. The main organizers of the events were Pavol Borià ¡ and Ladislav Snopko, and the festival was the first open-air festival in Czechoslovak Socialist Republic ever. The music columnist LubomÃÂr Dorà ¯à ¾ka called him "Czechoslovak Woodstock" ().
The idea to organize the Koncert mladosti festival originated in March 1976 at the Atlas klub. After a concert, Ladislav "Agnes" Snopko and Paþo Borià ¡, while drinking wine in the club's kitchen, talked about the idea of organizing a larger event at the Amphitheater Pezinok. After positive feedback from others, Borià ¡ and Snopko set about preparing the festival. Koncerty mladosti were an unprecedented cultural event, where top Czech-Slovak representatives of folk, rock and jazz performed â among other folk singers and VladimÃÂr Merta, Petr Lutka, Vlasta Tà Âeà ¡à Âák, VladimÃÂr Veit, Pepa Nos, Miloà ¡ Janouà ¡ek, Dagmar Andrtová and Zuzana Homolová, folk-rock band Marsyas, rock Collegium musicum, Jaro Filip, Vladimir Mià ¡ÃÂk's band Etc... debut concert, pop-rock Modus, jazzmen Gabriel JonÃ¡à ¡ and Pavol Kozma, jazz-rock bands Bohemia and Energit, including an offshoot, the Andrà ¡t/Viklický duo. The state media called the festival the festival of defiance against red normalization regime, the entrance fee cost 25 KÃÂs and during both years it was supposedly (according to Pavol Borià ¡) visited by 4,500 people.
In 1977, the moderators of the festival were Ladislav Snopko and Slávek JÃÂà ¡a. After Jaroslav Hutka sang the song "HavlÃÂÃÂku Havle", the visitors were anti-Bolshevik and thought about marching "against everything". The presenters calmed the situation by showing the film Yellow Submarine by the British music group The Beatles, which began with the notes of the French national anthem and the song "All You Need Is Love".
In 1978, a third year of the festival was planned, but it was eventually cancelled.
The atmosphere of the events was captured by photographer Ján à  trba and they were part of various commemorative exhibitions and books. Author of the posters of both years is Oliver Solga.
On 20 September 1997, after 20 years, the Pezinok Cultural Center organized a commemorative event, at which Emil Viklický, Fedor Freà ¡o, Vlasta Tà Âeà ¡à Âák, Jià ÂàDÃÂdeÃÂek, DÃ¡à ¡a Voà Âková, Pepa Nos, Radim HladÃÂk, Boris Urbánek, Roman Pokorný, Andrej à  eban, Marcel Buntaj, Oskar Rózsa, Luboà ¡ Andrà ¡t, ZdenÃÂk Tichota and Ramblin Rex from the United States performed with local support bands Slide Return and Alarm. In 2007, memorial concert in Schaubmar's Mill was organized by P.R.D. civil association, during which the new book Koncert mladosti '76 â '77 â ÃÂeskoslovenský Woodstock was baptized. In 2016 was held six-hours long Koncert mladosti 40 event.
