Antonin Rössler–Rosetti (1750 – 1792) is a czech music composer that spent most of his life abroad. This clarinet concerto was published by prof. Jiri Kratochvil in 1976 after some years of inquiry. Thanks to an exceptional uality of this pieces, it was soon put side by side to Kramar´s concerto. Our edition is not only revised but also gathers information from the last musicology researches and therefore completely changes the point of view at Rössler´s life and work. A piano part and a part for solo instrument are included.
