The brimborium around Johann Strauß blindly makes it blind in this country: in this year’s cultural calendar not only the Viennese waltz king is noted as anniversary. Among other things, it is also important to celebrate the 150th birthday of the French composer engraving Maurice Ravel. And then there would be the 50th anniversary of the death of the last great symphonist from Russia: Dmitri Schostakovich.
