Mich�l Yost, a Parisian by birth, was a famous French clarinet virtuoso in his time. He is regarded as one of France's first important clarinetists and as the co-founder of the French school of clarinet playing and gained renown beyond France's borders already during his lifetime. Along with clarinet chamber music and a collection of �tudes that is no longer extant, we know of fourteen clarinet concertos by Yost, some of which he composed in collaboration with the German composer and Paris resident Johann Christoph Vogel.
