Gena, Jouni Kaipainen’s first solo work for the accordion, was named after the accordion-playing crocodile in Eduard Uspensky’s storybook. From Gena’s thoughtful moods and dizzying virtuosity the audience is thrown right into the middle of a dramatic sea battle with Michel Corrette’s Combat Naval, Divertimento No. 2, a piece originally arranged for cembalo.

Radioflakes, the eponym of the concert, reflects the struggle of accordions between aggressive sound energy, carefree radio scanning and the rhythmic swing that is characteristic of the instrument. Radio waves deliver Bach’s orchestral and brilliant Partita in D-Major, after which the solo part of the concert culminates with a rendition of Liszt’s racing, virtuosic La Campanella. The concert will conclude with a newly commissioned piece for guitar and accordion by Kimmo Hakola.
