Maurice Ravel was a perfectionistic, somewhat secretive and super chic composer who loved to entertain his friends and also spent a lot of time in solitude. He seemed to compose “in his mind” before he put it on paper. He thought that he composed too little. His masterpiece Bolero may have been conceived during a trip in Canada and the USA, in 1928.
Here is Gaspard de la Nuit, by Ravel, played by Ivo Pogorelich.
