Wojciech Kilar was one of the representatives of the 'Polish School of Composition' – a term used by the music critics (initially by those from Germany, for that is where the name was coined) to describe the young composers working between the 1950s and 1960s, who radically broke with socialist realism. They would present their musical ideas at festivals, predominantly at Warsaw Autumn, where they would be received by a vast part of their contemporary audience (and critics) as iconoclastic, clamorous, and disrespectful towards tradition.
One of the symbols of such renouncement of traditions is Riff 62 (written in 1962, as the title implies) which reaches out to the style of Jazz. We hear a lot of brass instruments, a choice rarely made by the old music masters: 2 clarinets, 3 saxophones, 4 trumpets, and 4 trombones, next to piano solo, two percussion ensembles with vibraphone-xylorimba and leather instruments, as well as 36 violins and 12 double basses. The premiere performance of Riff 62 took place at the Warsaw Autumn. The musicians of the Symphony Orchestra of the Silesian Philharmonic, with Karol Stryja as conductor, had to play an encore, an occurrence which is uncommon at contemporary music festivals. In Riff, one is able to find the elements that would later keep recurring in the compositions of the Lvivian-Silesian artist: there is the unrestrained vitality, materializing in sudden eruptions of sound, and on the other hand – the simplicity and moderation, expressed through a limited range of sounds used by the composer.
Riff 62 was dedicated to Nadia Boulanger, a renowned Parisian composition teacher, who educated many of the classics of the 20th-century music, to name but a few: Phillip Glass, Astor Piazzola, Pierre Henry, Grażyna Błażewicz, and Aaron Copeland. Kilar attended her classes in 1959 when he travelled to Paris on a scholarship financed by the French government.
