Clarinet virtuoso Iwan M�ller succeeded in developing the possibilities of his instrument beyond it's limitations in Mozart's time into the modern clarinet, though his compositions have long been overlooked. The beautifully proportioned Clarinet Quartets Nos 1 and 2 form a complementary pair, placing lyrical ease and virtuoso refinement into 'impossible' keys as a demonstration of M�ller's innovations. The remaining works often follow an Italianate bel canto style, while his popular Souvenir de Dobb�ran is a prototype of the musical postcard genre.
